Techno-economic analysis of unsaturated polyester production from waste PET / Tehno-ekonomska analiza proizvodnje nezasićenih poliestara iz otpadnog PET-a
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
Unsaturated polyester resins (UPe) were synthesized from maleic anhydride and products of glycolysis, obtained by polyethylene terephthalate (PET) depolymerization with dipropylene glycol (DPG) in the presence of tetrabutyl ...
Analysis of fracture behaviour of thin s316l stainless steel plates
(Institut za ispitivanje materijala, Beograd, 2017)
In this paper are presented experimental analyses of the behaviour of 316L stainless steel in regard to fracture, according to standard methods of investigation on modified tensile C(T) specimens. The S316L alloy is selected ...
Microstructure evolution of the hot-rolled modified AA 5083 alloys during the two stage thermal treatment
(Savez inženjera metalurgije Srbije, Beograd, 2011)
The effects of the two stage heat treatment on the structure of two hot-rolled 5083 aluminum alloys without and with 0.12% Zr addition were investigated. Combination of the metallographic and transmission electron microscopy ...
