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 ...
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. ...
Analysis of the effects of butt welded joints on a carrying capacity of a structure tank / Analiza uticaja sučeono zavarenih spojeva na nosivost konstrukcije rezervoara
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
In the present paper, after calculation using the Finite Element Method (FEM), stress distribution on the model of a part of the pressure-tank mantle without welded joints (WJ), with transversal WJ, longitudinal WJ and ...
Impedance characteristics of aluminum with sol-gel ceria protective coating during the exposure to chloride corrosion agent / Impedansni odgovor aluminijuma sa zaštitnom prevlakom oksida cerijuma tokom izlaganja hloridnoj korozionoj sredini
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
Electrochemical impedance characteristics of bare Al and Al with CeO2 coating prepared sol-gel procedure from the ceria sol are investigated. The corrosion behavior is monitored during the exposure to 3 wt. % NaCl aqueous ...

PtAu catalyst with enhanced activity for formic acid oxidation / PtAu katalizator sa poboljšanom aktivnošću za reakciju oksidacije mravlje kiseline
(Engineering Society for Corrosion, Belgrade, Serbia, 2018)
PtAu systems are recognized as good catalysts for the oxidation of formic acid electrooxidation, which is investigated as a possible anodic reaction in low-temperature fuel cells. In this research, bimetallic PtAu ...
Determination of activation energy for static recrystallization using multipass continuous cooling torsion test
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Two microalloyed steels (Nb low carbon and V medium carbon) were tested by means of multistage continuous cooling torsion with aim to evaluate the interpass recrystallization data, by means of Tnr (temperature of ...
Solvatochromism of 5-(4-substituted arylazo)-4-phenyl-6-methyl-3-cyano-2-pyridones / Solvatohromizam 5-(4-supstituisanih arilazo)-4-fenil-6-metil-3-cijano-2-piridona
(Engineering Society for Corrosion, Belgrade, Serbia, 2018)
Eight 5-(4-substituted arylazo)-4-phenyl-6-methyl-3-cyano-2-pyridones were synthesized by reaction of benzoylacetone and arendiazonium salt, followed by condensation with cyanoacetamide. Absorption spectra of all azo ...
Integrity assessment of reverse engineered ti-6al-4v eli total hip replacement implant
(Society for Structural Integrity and Life, Institute for Material Testing, 2019)
Total hip replacement implants are used as an artificial replacement for disfunctional hips in order to sustain joint movement. Chosen material and design of total hip replacement are the most influential factors for ...
Effect of vibration on the variation of residual stresses and impact energy in butt-welded joints / Uticaj vibracija na promenu zaostalih napona i energije udara kod sučeono zavarenih spojeva
(Society for Structural Integrity and Life, Institute for Material Testing, 2012)
The effect of vibration on the variation of residual stresses in butt-welded steel plates and on the impact energy in characteristic zones of a welded joint is analysed in this paper. An important segment occurring as a ...
