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 effect of cooling rate of slag from primary copper production in the valorization of copper in the flotation process
(Savez inženjera metalurgije Srbije, Beograd, 2015)
Technological procedure of slow cooling slag from primary copper production is applied in the purpose of copper recovery in the level of 98.5% to blister. This technological procedure is divided into two phases, first slow ...
Effect of process parameters on the phase transformation kinetics in copper-based alloys and composites
(Metallurgical & Materials Engineering, 2020)
Copper-based alloys and composites, owing to their convenient properties, are being considered essential materials in various industries. Since copper possesses an ability to develop high corrosion resistance, putting it ...
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 ...
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. ...
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 ...
The effect of calcinated hydroxyapatite and magnesium doped hydroxyapatite as fillers on the mechanical properties of a model bisgma/tegdma dental composite initially and after aging
(Savez inženjera metalurgije Srbije, Beograd, 2018)
This study aimed to investigate the possibility of modifying model BisGMA/TEGDMA dental composite by substituting 10 wt. % of conventional glass fillers with bioactive fillers based on calcinated nanosized hydroxyapatite ...
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. ...
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 ...
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 ...
