Bisphenol a removal from aqueous solution using fine alpha-fe2o3 particles
(Savez inženjera metalurgije Srbije, Beograd, 2018)
Iron(III) oxide particles (alpha-Fe2O3) were obtained from ferrous chloride (FeCl3 center dot 6H(2)O) precursor using ammonium hydroxide as a precipitating agent and particles were calcined at 700 degrees C for 4 h. ...
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 ...

(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 ...
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 ...
Integrated procedure for recycling and valorization of useful components from secondary raw materials based on hard metals
(Savez inženjera metalurgije Srbije, Beograd, 2017)
Wide application of hard metals requires increased consumption of their constituents. Their high cost and scarcity impose the need for finding new, both ecologically and economically justified ways for their production. ...
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 ...
Defect formation during synthesis and welding of silver nanowires for solar cell applications
(Savez inženjera metalurgije Srbije, Beograd, 2019)
Structural defects such as stacking faults and twins, observed in many face-centered cubic (FCC) structured metals and alloys with low stacking fault energies, in general, play an important role in microstructure evolution, ...
Some aspects of physical metallurgy of microalloyed steels
(Savez inženjera metalurgije Srbije, Beograd, 2019)
Some aspects of deformation, precipitation, and recrystallization behavior in medium carbon V-microalloyed and low carbon Nb/Ti-microalloyed steels are presented in the paper. Changes in microstructure are explained together ...
Investigation of copper(i) sulphide leaching in oxidative hydrochloric acid solution
(Savez inženjera metalurgije Srbije, Beograd, 2015)
Present work is focused on the copper (I) sulphide leaching with sodium chloride in hydrochloric acid solution and with introduction of gaseous oxygen. Chemical reactions of leaching and their thermodynamic probabilities ...
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 ...
