Veza između mikrostrukture, faznog sastava i mehaničkih svojstava termo-izolacionih veziva na bazi otpadnog materijala / Correlation between microstructure, phase composition and mechanical properties of thermo-insulation bonding agents based on waste material
(Univerzitet u Nišu, Niš, 2012)
Konstrukcioni kompoziti - termo-izolaciona i/ili visoko-temperaturna veziva u kojima je leteći pepeo, kao potencijalno štetna materija za okolinu, kombinovan sa običnim i vatrostalnim cementom predstavlja jednu sasvim novu ...
Korozione pukotine od zaostalog topitelja posle lemljenja tankih listova na jednoj umetničkoj stolnoj lampi / Corrodive cracks from flux residuals after brazing of thin leaves at an artistic desk lamp
(Inženjersko društvo za koroziju, Beograd, 2018)
Izrada jednog umetničkog dela obično uključuje brojne različite tehnologije. To podrazumeva da je za razumevanje eventualno prisutnih nepravilnosti potrebno znati puno tehničkih detalja. Tehnologija lemljenja je jedna od ...
Semi-empirical software for the aluminothermic and carbothermic reactions
(Savez inženjera metalurgije Srbije, Beograd, 2014)
Understanding the reaction thermochemistry as well as formatting the empirical data about element distribution in gas-metal-slag phases is essential for creating a good model for aluminothermic and carbothermic reaction. ...
