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 ...
The recycling of high magnesium aluminum alloys estimation of the most reliable procedure
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Aluminum is one of the most recyclable materials. Namely, the properties of aluminum are not affected by the recycling and reuse, thus enable that high value of the metal is maintained after reprocessing. The re-smelting ...
A model for predicting fracture toughness in overaged 7000 alloy forgings
(Savez inženjera metalurgije Srbije, Beograd, 2007)
An attempt to develop a multiple micromechanism-based model for predicting plane-strain fracture toughness, KIc, of overaged 7000 alloy forgings has been made. The proposed model reveals the quantitative relations between ...
Optimisation of ferriferous dust and mud preparation acts from iron and steel production on purpose of returning to primary processes / Optimizacija postupaka pripreme železonosnih prašina i muljeva iz proizvodnje gvožđa i čelika u cilju vraćanja u primarne procese
(Savez inženjera metalurgije Srbije, Beograd, 2004)
In this paper detailed characterization of ferriferous dust and mud which originated from aglomerization, blast- furnace and converter process in Iron-works Smederevo were shown. Optimization of method peletization was ...
Experimental and numerical evaluation of a steamline behaviour using local approach
(Croatian Metallurgical Society, 2007)
Results of the experimental and numerical comparative analysis of steamline pipes have been presented. New pipes and the pipes used for more than 117,000 hours at 540 degrees C under pressure of 42 bars have been simultaneously ...
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 ...
Fuel consumption analysis in cooper melting and refining plants / Analiza potrošnje energenata u pogonima za topljenje i rafinaciju bakra
(Savez inženjera metalurgije Srbije, Beograd, 2004)
Cathode cooper production and refining include significant consumption of almost all-conventional fuel types. The given consumption is high in specific and in nominal way. Especially high fuel value content is on Cathode ...
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 ...
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 ...
