AB  - Microstructure assessment is crucial for the design and production of high-quality alloys such as cast aluminum alloy ingots. Along with the effect of a more homogeneous microstructure to result in much better mechanical properties, better as-cast alloy quality indicates a higher efficiency of the aluminum alloys production process. During the aluminum alloy solidification process many microstructural defects can occur, which deteriorate the mechanical properties and hence decrease the usability of such an ingot. Application of the electromagnetic field during the vertical continuous casting process significantly reduces occurrence of these defects. In the present study, EN AW 7075 alloy samples were cast with and without application of an electromagnetic field and examined regarding the microstructure, electrical conductivity, and changes in the phase composition. The obtained results clearly show that it is possible to decrease or avoid casting defects by the electromagnetic field application as verified by the microstructure characterization and quantification, electrical conductivity tests and differential thermal analysis (DTA).

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  - This paper presents the investigation into the possibility for application of production process for casting aluminum alloys under the influence of electromagnetic field. The presented results were obtained from microstructure examination of Al alloy 2024 ingots casted with or without electromagnetic field. The microstructure characterization shows that under the influence of low-frequency (30-50 Hz) electromagnetic field it is possible to obtain finer and more homogeneous microstructure with reduced porosity. In the end, it is obvious in which way the operation parameters should be varied in order to get a good quality of ingots.

AB  - Proučavana je mikrostruktura odlivaka koji su dobijeni kontinuiranim livenjem Al legure EN AW 2024 čija se kristalizacija odvijala bez uticaja i pod uticajem elektromagnetnog polja malih frekvencija. Mikrostrukturna analiza pokazuje da se pod dejstvom niskofrekventnog elektromagnetnog polja dobija finija i po preseku homogenija mikrostruktura. S obzirom da su ovo kod nas prva primenjena istraživanja uticaja elektromagnetnog polja na proces očvršćavanja, rezultati jasno ukazuju u kom pravcu treba menjati radne parametre kako bi se dobili odlivci optimalnog kvaliteta.
AB  - The results presented in this paper were obtained from microstructure examination of Al alloy 2024 ingots casted with or without low-frequency electromagnetic field. The microstructure characterization shows that it is possible to get finer and more homogeneous microstructure through the entire cross section of ingots casted with electromagnetic field, compared to ingots casted without electromagnetic field. Although, this is our first examination into the effect of electromagnetic field on process of solidification, it is obvious in which way the operation parameters should be varied in order to get a good quality of ingots.
