AB  - The investigation here is aimed to examine the structural and mechanical changes that might have occurred during the hot forging process, a process to obtain a surgical hip implant, and the subsequent heat treatment. Microstructural characterization, morphological and semi-quantitative chemical analyses have been accomplished using an optical and scanning electron microscope. Chemical analyses of all surfaces obtained by the dotted method in all analyzed samples have shown the approximate equal content of aluminum, titanium, vanadium, iron, and silicon. Tensile testing and measurements were following obtained microstructure, showing the uniformity of microstructure and properties along the forging part, as well as over its cross section. All tests proved that hot forging could be a suitable procedure for surgical implants processing.

AB  - In this research, results of experimental investigations and physical model were used as the input variables for numerical analysis of the ironing strip drawing process by application of lubricants. The numerical simulation was realized in the specialized applicative software Simufact.forming. By applying the software for the 3D modeling, a model of the tool element assembly was made, which served as the starting basis for numerical simulation by application of the Finite Element Method. Experimental values of the friction coefficient for each type of lubricants and the contact pressures were used for defining the contact conditions. Numerical simulation of the drawing process was done for each type of the contact conditions between the tool's elements and the thin sheet sample. After conducted tests comparison of experimental and numerical results of the drawing forces in different contact conditions was done. Comparison was done with taking into account appearance of galling due to difficult drawing process conditions. By comparation of numerical results to the experimental one it is possible to interpret what types of simplifications were adopted in creating the experimental physical-tribological model.

AB  - The analysis of material and energy balance can be done using concept of exergy, which is
a measure of available energy in the system [1]. Exergy losses indicate the place of
degradation in the process; thus, it implies improving of selected process.
The aluminothermic reduction process is an attractive method for immobilization of
hazardous waste, and for utilization of valuable elements from the waste [2]. The exergy
calculation relies on the material and energy balance calculation and standard chemical
exergy of the elements. For the purpose of material, energy, and exergy balance calculation
discrete non-commercial software was developed [3]. The waste materials used in these
calculations are Electric-arc furnace dust (EAFD, mostly Fe and Zn oxides) and the Mill
scale (mostly Fe oxides) [4].
Calculated exergy efficiency for aluminothermic processing of waste was 94.6%. All the
heat released by exothermic reactions was used for producing the iron, the slag and the
crude ZnO dust. Comparing to the conventional carbothermic reduction process in the DC
electric-arc furnace with the same materials (for which exergy efficiency was 56.5%) this
is much higher. The irreversible exergy losses of the aluminothermic process are 398.2
kWh/t of produced iron. The further processing of slag and dust is required, as well as in
the case of the carbothermic reduction process, so that the real value of exergy efficiency
of the process will be somewhat lower than the calculated.

AB  - Modern industrial product design implies presence of many different materials. Consequently, in the recycling process, shredding and separation procedures are applied. However, all materials cannot be completely separated; therefore, there is a contamination in the recycling streams. The quality of the materials streams can be reduced in each of the following recycling steps. These qualitative losses cannot be described by material balance. This paper presents the concept of exergy as a measure of quality losses, and gives the methods for the calculation of the exergy content and the exergy loss. Losses attributed to the recycling or material losses, material contamination losses and dilution requirements can be used as indicators for the materials quality loss as well as for the resource efficiency in the production systems. In this paper, the example of calculations on the steel scrap is presented.

AB  - Simulating the reactions in a complex system can lead to self-sustaining and energy efficient treatment of wastes in recycling promoting manner. In this contribution, the synergic combination of electric arc furnace dust (EAFD), mill scale, and secondary aluminum, in a form of waste foil, was researched aiming to use exothermal energy of reactions and to obtain environmentally favorable products. The secondary aluminum in the form of foil was prepared in different ways in order to develop aluminum surface and to be suitable for aluminothermic reactions. The commercial aluminum powder was used to determine optimal conditions using full factorial experiment design. After that, research was performed on aluminothermic reactions with the aluminum powder obtained from secondary aluminum foils. Results show that the secondary aluminum can be successfully used for a treatment of oxides bearing hazardous wastes in an energy efficient and environmentally friendly manner. The comparative life-cycle assessment revealed several advantages of using the secondary aluminum foil as a reduction agent compared to the conventional recycling of the secondary aluminum foil.

AB  - Refractory sulphide-barite ore was reduced with carbon in order to release lead, zinc, and copper sulphide from barite-pyrite base. Mineralogical investigations showed that due to the complex structural-textural relationships of lead, copper and zinc minerals with gangue minerals, it is not possible to enrich the ore using the conventional methods of mineral processing. The influence of temperature and time was studied to optimize the conditions, and to determine the kinetics of the barite reduction. The maximum removal of barite from ore was 96.7% at 900oC after 180 min. Chemically controlled kinetic model showed the best compliance with the experimental data. An activation energy of 142 kJ/mol was found.

AB  - Elektromagnetni postupak livenja zasniva se na teoriji metalurških procesa i magnetohidrodinamici. Prilikom livenja u prisustvu elektromagnetnog polja naizmenična struja generiše vremenski promenljivo mognetno polje u istopljenoj masi što povećava indukovanu struju u rastopu. Rastop metala je pod uticajem elektromagnetne sile koja je prouzrokovana interakcijom indukovane struje i magnetnog polja. Elektromagnetna sila izaziva veći protok fluida, prinudnu  konvekciju, ravnomernije temperaturno polje i slabiji uticaj gravitacije. Na ovaj način se menjaju uslovi očvršćavanja. Dobijeni odlivci su kvalitetniji, struktura je finija i uniformnija po preseku. Zbog smanjenog kontaktnog pritiska, (što je takođe posledica delovanja elektromagnetnog polja) između kalupa i metala, kvalitet površine je poboljšan tako da nije potrebna veća dodatna mašinska obrada. U svetu postoje određena istraživanja u oblasti elektromagnetnog postupka  livenja, ali je malo pažnje posvećeno karakterizaciji mikrostrukture i mehaničkih svojstava tako dobijenih odlivaka. Ovaj rad treba da doprinese boljem poznavanju uticaja elektromagnetnog polja na dobijenu mikrostrukturu (morfologiju, veličinu zrna, raspodelu i udeo dobijenih faza) i ostale karakteristike dobijenih odlivaka.  Izabrana legura EN AW 7075 ima široku primenu u industriji, termički je obradiva i namenjena je za plastičnu preradu odnosno kovanje. Proizvodnja ove legure je dugotrajna i skupa, a prate je nedostaci tipa poroznosti, toplih pukotina i neujednačenosti u veličini zrna. Ove metalurške greške utiču na pogoršanje mehaničkih svojstava i kvaliteta dobijenih odlivaka. U cilju smanjenja ovih grešaka još u livenom stanju neophodno je primeniti odgovarajući postupak livenja  sa optimalnim radnim parametrima. Da bi se ispitao uticaj  elektromagnetnog polja prilikom livenja upoređeni su uzorci odliveni bez dejstva polja i pod dejstvom polja različite frekvencije 10, 15, 20 i 30 Hz. Rezultati ispitivanja mikrostrukture i mehaničkih svojstava pokazuju da je primenom elektromagnetnog polja moguće dobiti finiju i homogeniju mikrostrukturu, a samim tim i bolja mehanička svojstva. Dobijeni rezultati SEM/EDX, DTA analize kao i rezultati  merenja elektroprovodljivosti i određivanja hemijske segregacije su prikazani i upoređeni. Primena matematičkih modela u obradi rezultata i numerička simulacija procesa toplog kovanja su urađeni prateći svetske trendove, a njihova praktična primena ima za cilj uštedu energije, smanjenje škarta i potrošnju sirovina Dobijeni rezultati se mogu koristiti za proširenje baza podataka primenjenih modela.

AB  - Electromagnetic casting (EMC) is the technology developed as by combining the magnetic hydrodynamics and casting technique. Electromagnetic forces, arising from the interaction of Eddy currents induced in the metal by inductor magnetic field, cause  an increased flow of  the  fluid,  forced  convection,  more  uniform  temperature  field  and  weak  gravitation influence thus changing the conditions of solidification. The advantage of EMC reflects in   obtaining  a  better  quality  of  ingots  compared  to  convent ional  continuous  casting  process.   Namely,  the  structure  obtained  is  finer  and  more  uniform  through  the  cross  section,  with reduced  segregation  of  alloy  element  and  porosity.  Apart  from  that,  due  to  the  reduced contact  pressure  (result  of  electromagnetic  field  effect)  between  the  mould  and  the  metal,   the quality of ingot surface is improved, having no need for additional machine processing. The  investigations  conducted  in  the  world  were   aimed  to  investigate  the  effect  of electromagnetic,  magnetic  and  hydrodynamic  phenomena  on  Al  ingots,  but  very  little   attention was given to the characterization of microstructure and mechanical properties.   This work, should contribute to better knowledge of the  effect of electromagnetic field on the obtained microstructure (morphology, size, volume fraction and distribution of phases) and properties of Al alloys. The chosen alloy was EN AW  7075 heat treatable, intended for  forge  with  wide  industry  use.  It  is  characterized  by  a  number  of  defects  that  occur  during  the  solidific ation  process:  porosity,  hot  cracks,  non  -uniformal  grain  size  and  crystal  segregation.  Since  the  quality  of  final  product  is  directly  affected  by  these  defects  it  is  necessary  to  prevent  or  reduce  their  appearance  by  the  choice  of  the  appropriate  process  and optimal parameters of casting. To compare the results of electromagnetic casting, (with different  operating  parameters),  the  process  of  vertical  continual  casting  without  the   presence  of  low  frequency  electromagnetic  field  was  selected.  The  results  were obtained  from  microstructure  and  mechanical  examination  of  Al  alloy  7075 ingots  casted  with  and  without  low-frequency  electromagnetic  field.  The  microstructure characterization  shows that it is possible to obtain finer and more homogeneous microstructure   through the entire cross section of ingots casted with electromagnetic field, compared to ingots casted without electromagnetic   field.   As   the   consequence   of   microstructure-mechanical   properties correlation,  the  use  of  electromagnetic  field  improved  the  mechanical  properties,  as  well.   The results obtained from SEM/EDX, DTA,electrical conductivity measurement were also shoved and compared. The chemometric approach for mechanical properties prediction and numerical  simulation  of  the  forging  process  of  EN  AW  7075  alloy  were  carried  out following the latest world trends and the obtained results can be used as a basis for further  training   by  expanding  of  database  of  derived  models. This  doctoral  dissertation  is  the  investigation result of the project: “The development  of  casting  technologies  under  the influence  of  electromagnetic  field  and  technologies  of  hot  plastic  forming  of  7000  series aluminium alloys for special purposes” TR34002, leaded by professor Zvonko Gulišija, in the  frame  of  Technological  Development Program,  funded  by  The  Ministry  of  Education, Science and Technological Development of the Republic of Serbia, in the period from 2011 to June 2016.

Usled toga, kvalitet materijala može se smanjivati u svakom narednom koraku reciklaže. Pored toga, resursi nižeg kvaliteta proizvedeni su iz resursnih tokova koji su u izvornom obliku imali viši kvalitet. Ovakvi gubici kvaliteta ne mogu da se mere masenim bilansima, isto kao što se degradacija kvaliteta ne može prikazati samo merenjem mase. Za proračun svih gubitaka prouzrokovanih reciklažnom kontaminacijom, svi dalji procesi reciklaže potrebni da bi se materijali vratili nazad u resursne cikluse moraju biti uključeni. U ovom radu prikazan je metod za izračunavanje eksergijskog sadržaja i eksergijskog gubitka metalnih rastvora u toku iskorišćnja i reciklaže. Gubici pripisani reciklaži ili tačnije materijalni gubici, gubici usled kontaminacije drugim metalima i posledično potreba za razblaživanjem, mogu se koristiti kao indikatori gubitka kvaliteta materijala i efikasnosti korišćenja resursa u proizvodnim sistemima. Dakle, ovde je eksergija predložena kao mera efikasnosti korišćenja resursa. U radu su proračuni eksergijskih gubitaka tokom reciklaže prikazani na primeru aluminijumskog otpada.
AB  - Materials for recycling always contain a certain degree of contamination. The presence of impurities i.e. contamination in the recycling streams causes a change in the composition of the original materials to recycle. As a result, the quality of materials can be reduced in each successive step of recycling. In addition, the resources of lower quality are produced from the resource flows which had a higher quality in their original form. This kind losses of quality cannot be measured by mass balance, as well as the quality degradation not only can display measurements of mass. For the calculation of all losses caused by recycling contaminations, all further recycling processes required to return the materials back into resource cycles must be included. The method for calculating the exergy content and exergy losses of metal solutions during recovery and recycling is presented in this paper. The losses attributed to recycling, namely the material losses, the contamination losses with other metals, and the consequent need for dilution can be used as indicators of the quality loss of materials and of the efficiency of resource use in product systems. Therefore, exergy is proposed here as a measure of the efficiency of resources use. This paper presents calculations of exergy losses during recycling shown in the case of aluminum waste.

AB  - In this study the mechanical properties (reduction of area, S-0, tensile strength, R-m, yield strength, R-p, and elongation, A) of EN AW 7075 aluminum alloy obtained by electromagnetic casting were investigated at different operating parameters: frequency (V), field strength (T) and current intensity (I). The predictive mathematical models using Response Surface Methodology, with second order polynomial (SOP) regression models, and Artificial Neural Network model (ANN), were afterwards compared to obtained experimental results. Analysis of variance and post-hoc Tukey's HSD test at 95% confidence limit ("honestly significant differences") have been utilised to show significant differences between various samples. SOP models showed good prediction capabilities, with high coefficients of determination (r(2)), 0.531-0.977, while ANN model performed even better prediction accuracy: 0.800-0.992. The optimal samples were chosen depending on mechanical properties of the product (S-0 = 50.49mm(2), R-m = 405.75Nmm(-2), R-p = 302.49Nmm(-2), A = 6.86%), using optimal operating parameters (V = 30 Hz, I = 250 A, T = 18 x 10(-3) At).

AB  - Postupci prerade sekundarnih sirovina bakra uključuju dva osnovna stupnja: pripremu bakarnih otpadaka i njihovu dalju metaluršku preradu. Za pripremu bakarnih otpadaka koriste se različiti postupci u zavisnosti od vrste i kvaliteta sekundarne sirovine. Sve operacije pripreme utiču na kvalitet metalurške prerade, odnosno na kvalitet proizvoda. Za topljenje pripremljenih sekundarnih sirovina u cilju dobijanja legura na bazi bakra koriste se razni agregati: šahtne peći, konvertori, plamene lončaste i koritaste plamene peći, kratke bubnjaste peći i električne peći (elektrolučne, elektrootporne, indukcione).
AB  - Procedures for copper secondary raw materials processing include two basic stages: pretreatment of the copper waste and its further metallurgical processing. For copper waste pretreatment technology, there are different applied procedures depending on the type of raw material.

abstract = "Postupci prerade sekundarnih sirovina bakra uključuju dva osnovna stupnja: pripremu bakarnih otpadaka i njihovu dalju metaluršku preradu. Za pripremu bakarnih otpadaka koriste se različiti postupci u zavisnosti od vrste i kvaliteta sekundarne sirovine. Sve operacije pripreme utiču na kvalitet metalurške prerade, odnosno na kvalitet proizvoda. Za topljenje pripremljenih sekundarnih sirovina u cilju dobijanja legura na bazi bakra koriste se razni agregati: šahtne peći, konvertori, plamene lončaste i koritaste plamene peći, kratke bubnjaste peći i električne peći (elektrolučne, elektrootporne, indukcione)., Procedures for copper secondary raw materials processing include two basic stages: pretreatment of the copper waste and its further metallurgical processing. For copper waste pretreatment technology, there are different applied procedures depending on the type of raw material. All operations of pretreatment are influencing the quality of metallurgical processing. For metallurgical processing of raw materials prepared for the purpose of obtaining copper and copper alloys the shaft, flaming and short-drum furnaces, converters and electric furnaces (electric resistant, electric arc and induction furnaces) are used.",

AB  - With the recently increased use of magnesium alloys, especially in the automotive industry, a large quantity of generated waste, based on magnesium alloys, is expected. Such a waste often contains many impurities such as oil, paint, moisture, non-metallic fractions, oxides, Cu, Fe, etc. In this paper, two different methods for extracting magnesium from a highly contaminated waste are presented: the recycling of magnesium with flux and with the vacuum-distillation process. In addition, we present the process of pre-treating the contaminated magnesium waste that has proved to be a very important step in the recycling process for both economic and environmental reasons. The processing of post-consumer and contaminated magnesium scrap is described with a diagram, providing a sustainable and environmentally friendly procedure for the treatment of such wastes.

AB  - This work presents a way to obtain the better quality of EN AW 7075 aluminum high-strength alloy by application of electromagnetic field (EMF) during the casting process. In this way, the uniform fine-grained microstructure, and hence the better mechanical properties of the alloy can be achieved. The microstructure and mechanical characterization for samples obtained with and without EMF were performed. The application of numerical simulation for hot forging process, using appropriate software, is efficient and highly useful tool for problem prediction in industrial production, reducing the time and costs in the process of development of new products. The input data of high strength Al-alloy EN AW-7075 is used for simulation because it enables the development of parts with complex dimensions and shape.

Na temperaturi od 1200 °C i vakuumu od 3 KPa proces redukcije se završava za 2 h.

AB  - We present experimental investigations that define both the technological scheme of calcium production from limestone by aluminothermic process and the basic operating parameters of the particular technological phases. The limestone with high content of Mg, Na and K was used in the study. X-ray analysis reveals that the samples contain mainly calcite with small amount of dolomite. At first, the effects of temperature, time and granulometry on the calcium carbonate calcination were examined. The dissociation process was completed in 10-15 min at 1200 °C, and the dissociation rate increased with decreasing particle size down to 5 mm. Afterwards, the aluminothermic reduction process of calcium oxide was investigated. At a temperature of 1200 °C and vacuum of at least 3 kPa, the reduction process completed within 2 h. The chemical composition of calcium oxide and calcium showed increased content of magnesium oxide and alkaline oxides (especially sodium).

AB  - The microstructure and the mechanical properties of the samples obtained by conventional vertical continuous casting and electromagnetic casting of 7075 aluminum as-cast alloy were investigated. The better surface quality, more homogeneous alloying elements distribution and hence the microstructure and better mechanical properties were obtained in samples casted with electromagnetic field (EMF) compared with samples casted without EMF. The microstructure was analyzed by optical microscope and the variation of alloying elements, Zn and Mg, through the sample cross section was examined by chemical analysis. The mechanical properties of samples casted with and without electromagnetic field were determined using computerized materials testing machine Zwick/Roel Z 100.

The better surface quality, more homogeneous alloying elements distribution and hence the microstructure and better mechanical properties were obtained in samples casted with electromagnetic field (EMF) compared with samples casted without EMF. The microstructure was analyzed by optical microscope and the variation of alloying elements, Zn and Mg, through the sample cross section was examined by chemical analysis. The mechanical properties of samples casted with and without electromagnetic field were determined using computerized materials testing machine Zwick/Roel Z 100.",

AB  - The processes that take place at the liquid metal-sand mold interface during the casting and crystallization of metal were studied in this paper. The mold was made using the CO2 - Method, with the addition of active components, such as: MgO, TiO2, AIK(SO4)(2) and Na2SO4. At the liquid steel pouring temperature, these active components undergo decomposition in the mold, caused by heat release during pouring, Crystallization and cooling of castings. Silicates, which have an important influence on casting surface quality, are formed as a result of the interaction between the mould material and liquid steel.

AB  - For decades, the standard metallic materials for hip implants, besides the 316LVM stainless steel, were titanium- and cobalt/chromium-based alloys. Although bioinert, due to their corrosion resistance, they are not biocompatible. Contemporary surgical implants are no longer made solely from bioinert metals anymore, but with deposited bioactive hydroxyapatite (HAp) coatings. Hydroxyapatite is chemically identical with the mineral constituent of bones and teeth, which, besides its biocompatibility, provides bioactivity as well. The HAp limitations are, however, weak tensile strength and low fatigue resistance for long term loadings, if used alone. This is the reason for HAp to be deposited onto the surgical implant, and to enable its bioactivity, which means intergrowth with bones, and therefore the long-lasting and mechanical stable non-cemented prosthesis. This is important predominantly because of the need for such prostheses for younger population and a better life quality. There are several contemporary techniques that have been used for deposition of these coatings onto the metal implant. The possibilities of atmospheric plasma-spraying for obtaining stable HAp coatings on 316LVM stainless steel, ordinarily used as a standard material for hip implants production, are presented in this paper. The coatings of a commercially available hydroxyapatite powder were plasma-sprayed onto specimens of medical grade 316LVM stainless steel under various operating conditions. Optical microscopy was used for microstructure and porosity characterization, while the coating morphology and Ca/P ratio were analyzed using an SEM equipped with EDX. The coating microstructure varied from a porous to a glassy structure, depending on the operating conditions and coating thickness. Coating porosity was determined to be at the lower required limit requested for the bone-coating intergrowth possibility, but nevertheless adhesion measurements showed good results. The Ca/P ratio was determined for both as-deposited coatings and after ageing in distilled water for various time and temperature combination.

AB  - At the contact surface between the liquid metal and the mold wall a number of chemical and thermodynamical reactions were taken. The products of those reactions are spread out on both the sides, i.e., in the solidified metal or into the mold wall. The processes which took place in the casting mold-here made from sand mix, during the pouring of liquid metal, solidification and cooling down to room temperature, are pretty complex. The thermodynamic reactions at the contact surface of liquid metal/sand mold in the process of castings forming are discussed in this paper. Experiments were performed in molds made by CO2 sand casting process. As a pouring metal we used steels from an ordinary production program of a steel foundry, exactly it was the steel GS 50CrMo4, assigned by DIN. Some results obtained in our investigations during studying those processes are shown here.
