Dynamic recrystallization in M2 tool steel during friction welding
(Savez inženjera metalurgije Srbije, Beograd, 2005)
Friction welding of M2 tool steel and 1730 quenched and tempered steel was performed with the aim to reveal the origin of extremely fine martensitic grain in M2 steel after welding. Taking into account thermomechanical ...
Synthesis and sintering of Cu-Al2O3 nanocomposite powders produced by a thermochemical route
(Savez inženjera metalurgije Srbije, Beograd, 2007)
By hydrometallurgy and powder metallurgy along with prognosis of physical-chemical properties, a synthesis of new improved materials can be successfully performed with in advance pre-set properties which is conditioned by ...
Investigation of mechanism and kinetics of chalcopyrite concentrate oxidation process
(Croatian Metallurgical Society, 2008)
The oxidation process of chalcopyrite concentrate "Rudnik" (Serbia) was investigated by DTA-TG measurements under air conditions in the temperature range of 298 - 1173 K, as well as by XRD analysis of the oxidation products ...
The influence of thermomechanical treatment on recrystallization of AlMg4.5Cu0.5 alloy
(Savez inženjera metalurgije Srbije, Beograd, 2007)
Recrystallization behavior of an Al-Mg-Cu alloy (4.5 wt. %Mg and 0.45 wt %Cu) subjected to different thermomechanical treatments (TMTs) have been studied by means of light optical microscopy and hardness measurements. In ...

(Savez inženjera metalurgije Srbije, Beograd, 2006)
Thanks to fact that composite material have usefully characteristic two or more materials, they are becoming more and more substitute standard materials in every field of technique they start to. In this study static ...
Determination of AL2O3particle size in Cu-AL2O3 nanocomposite materials using UV spectrophotometry / Određivanje veličine čestica AL2O3 u nanokompozitnim materijalima iz sistema Cu-AL2O3 primenom UV spektrofotometrije
(Savez inženjera metalurgije Srbije, Beograd, 2008)
In order to achieve improved mechanical properties of dispersion strengthened nanocomposite, without influencing electrical and thermal conductivity it is necessary for dispersoide to be nano sized and uniformly distributed ...
Characterization of nano-powder morphology obtained by ultrasonic spray pyrolysis
(Savez inženjera metalurgije Srbije, Beograd, 2008)
Spherical nanosized particles of copper were synthesized by ultrasonic dispersion of solutions from copper sulphate in the temperature range of 800-900°C in hydrogen atmosphere. A controlled particle size was realized ...
