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 ...
Anti-tarnish silver alloys in system ag-cu-zn-si with the addition of aluminum
(Association of Metallurgical Engineers of Serbia AMES, 2018)
This paper presents investigations of aluminum addition influence on the corrosion characteristics of the sterling silver Ag-Cu-Zn-Si alloys. The procedure for obtaining Ag-Cu-Zn-Al-Si alloys in small ranges of predefined ...
Synthesis of novel wo3/zrsio4 catalysts for dehalogenation of halogenated hydrocarbons
(Savez inženjera metalurgije Srbije, Beograd, 2019)
This research aimed to develop a novel catalyst based on WO3/ZrSiO4 system for halogenated hydrocarbons processing. The production method of this catalyst involved extrusion and as such was simplified compared to thermo-chemical ...
Development of the universal tool for testing of tensile properties of hexagonal steel wire mesh for civil engineering
(Association of Metallurgical Engineers of Serbia AMES, 2018)
The developing of the universal tool for testing of tensile properties of hexagonal steel wire mesh for civil engineering is described in this paper. The developed tool allows repeated testing of hexagonal steel wire mesh ...
Synthesis of 4,6-dimethyl-3-cyano-2-pyridone catalysed by amino acids / Sinteza 4,6-dimetil-3-cijano-2-piridona katalizovana aminokiselinama
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
In this work the synthesis of 4,6-dimethyl-3-cyano-2-pyridone catalyzed by amino acids was studied. In the first part of the work, the optimization was carried out by varying the initial concentration of glycine, the molar ...
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 ...
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. ...
Behaviour of nionikral-70 in low-cycle fatigue
(Society for Structural Integrity and Life, Institute for Material Testing, 2017)
Experimental research on the behaviour of high-strength low-alloy steel ( HSLA)exposed to low-cycle fatigue (LCF) with controlled and fully reversible strain (Delta epsilon/2 = const, R epsilon =epsilon(min)/epsilon(max) ...
Influence of the Fe(III): Modified clinoptilolite on phosphorus leaching from different soil types / Uticaj Fe(III)- modifikovanog klinoptilolita na izluživanje fosfora iz različitih vrsta zemljišta
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
Influence of the iron(III)-modified clinoptilolite (FeCLI) on phosphorus leaching from two different Norwegian soil types (sand and clay loam soil) was studied using a column system at room temperature. FeCLI was used in ...
Immobilization of peroxidase from fresh horseradish extract for anthraquinone dye decolorization / Imobilizacija peroksidaze iz svežeg ekstrakta rena i primena u dekolorizaciji antrahinonskih boja
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
Synthetic dyes are used in all sectors of industry and represent a serious ecological problem. By the presence, anthraquinone dyes are right after the azo dyes. Unlike azo, anthraquinone dyes are considerably harder to ...
