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 ...

The influence of thermomechanical treatment and chemical composition on recrystallization of Al-Mg alloys
(Savez inženjera metalurgije Srbije, Beograd, 2007)
Recrystallization behaviour of AlMg3, AlMg4.5Mn and AlMg6Mn alloy plates subjected to different thermomechanical treatments (TMTs), has been studied by means of optical microscopy and hardness measurements. Applied two-stage ...
Influence of Cu and Mn content on the properties of Al-Mg4.5-(Mn,Cu) type alloy sheets
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Influence of Cu and Mn content on the grain structure, precipitation effects and mechanical properties of two Al-Mg4.5-(Mn,Cu) type sheets was considered. It was found that a variety of grain size can be obtained in alloy ...
FEM modeling of dynamic recrystallization in 304 stainless steel
