Influence of the fabrication process of copper matrix composites on cavitation erosion resistance
(Savez inženjera metalurgije Srbije, Beograd, 2017)
Copper matrix composites reinforced with ZrB2 particles were produced in two ways: by hot pressing (HP) and laser-sintering process. Powder mixture Cu-Zr-B was mechanically alloyed before densification processes. Variations ...

(Association of Metallurgical Engineers of Serbia, 2016)
This work presents the laboratory testing results of kinetics the oxidation process and sample processing of the sulphide polymetallic concentrate Blagojev Kamen. The aim of investigation is recovery of these types of raw ...
Treatment of dispersed iron-bearing raw materials and modeling of the protection systems against air-pollution
(Association of Metallurgical Engineers of Serbia, 2016)
Based on the analysis of the non-standard iron-bearing raw materials treatment process and the results of real composition measurements of the flue gas, the study of hazards by identification of harmful substances that ...
Algorithm for quantifying the particle size distribution of non-metallic inclusions formation in steel production
(Metallurgical & Materials Engineering, 2021)
When the quantitative characterization of non-metallic inclusions in steel is done and the effect of limiting factors is assessed, and based on that the possibility of reconstruction of the total content of non-metallic ...
Ni-pd/al(2)o(3) catalyst supported on reticulated ceramic foam for dry methane reforming
(Savez inženjera metalurgije Srbije, Beograd, 2015)
In the present study, Ni-Pd/Al2O3 catalyst supported on alpha-Al2O3 based foam was prepared and evaluated in the dry methane reforming process. Corresponding metal chlorides were deposited to the foam surface by impregnation ...
Estimation of phosphorus distribution ratio at the end of blowing in bof
(Metallurgical & Materials Engineering, 2021)
In integrated steel plants, the removal of phosphorous normally takes place during the primary basic oxygen furnace (BOF) steelmaking process. Phosphorous is usually introduced to the integrated steelmaking process through ...
Synthesis of nife2o4 nanofibers by joint sol-gel and electrospinning technique
(Savez inženjera metalurgije Srbije, Beograd, 2018)
In this study, electrospinning combined with sol-gel technique is applied in order to produce magnetic nickel ferrite (Ni-ferrite) nanofibers. The prepared Ni-ferrite gel was mixed with poly(vinylpyrrolidone) (PVP) solution ...
Kinetics of barite reduction from refractory barite-sulphide ore
(Savez inženjera metalurgije Srbije, Beograd, 2016)
Refractory sulphide-barite ore was reduced with carbon in order to release lead, zinc, and copper sulphide from barite-pyrite base. Mineralogical investigations showed that due to the complex structural-textural relationships ...
Numerical simulation of temperature field in the vertical bridgman method crystal growth
(Savez inženjera metalurgije Srbije, Beograd, 2015)
The mathematical model for heat transfer during the Bridgeman crystal growth, using the finite element method and the obtained result are presented. Some modifications to the method were introduced in order to incorporate ...
The influence of Mg and Mn content on abnormal grain growth in AA5182 type alloys
(Savez inženjera metalurgije Srbije, Beograd, 2019)
The occurrence of abnormal grain growth (AGG) in AA5182 alloy during annealing imposes severe restrictions on processing parameters and deteriorates mechanical properties. In this work, we investigated the effect of chemical ...
