Synthesis of α-Al2O3 based foams with improved properties as catalyst carriers
(Institute of Metals and Technology, 2014)
This paper explores the possibility of synthesising catalyst supports with improved properties. Alumina foams were produced with the polymer replication technique. Representative high- and low-temperature sintering ceramics ...
Examination of mechanical properties of acrilyc composite materials with different AL2O3 reinforcement by brazil test / Ispitivanje mehaničkih svojstava akrilatnih kompozitnih materijala sa različitim AL2O3 ojačanjima brazilskim testom
(Savez inženjera i tehničara Srbije, Beograd, 2019)
Composite materials based on UV-curing acrylates and various alumina-based reinforcements represent material that is suitable for the use in dentistry, but also in other areas. Composites were made using four different ...

Mechanical properties of two Al-Mg alloys manufactured by accumulative roll bonding (ARB) process
(Belgrade : Association of Metallurgical Engineers of Serbia (AMES), 2017)
The influence of alloying on the mechanical properties of AA5083 type Al-Mg
alloy sheets produced by accumulative roll bonding (ARB) process was studied.
Two investigated Al-Mg alloys: commercial AA5083 alloy with 4.2% ...
Age hardening potential of an Al-4.6 wt.% Mg alloy with Cu addition
(Belgrade : Institute of Technical Sciences of SASA, 2010)
The ageing behavior of an Al-4.6Mg-0.54Cu (in wt.%) alloy was studied after: (i) solution
treatment for 1h at 530°C, and (ii) annealing at 280°C for 3h. Both groups of the heat treated
specimens underwent further ...
Influence of an accumulative roll bonding (ARB) process on the properties of AA5083 Al-Mg alloy sheets
(Association of Metallurgical Engineers of Serbia AMES, 2014)
In this study, fully annealed AA5083 type alloy sheets with 1 mm in thickness
were processed by accumulative roll bonding (ARB) at room temperature, up to 6 ARB
cycles. It was found that microstructure was refined and ...
Characterization of tantalum coatings deposited using vacuum plasma spray process / Karakterizacija tantal prevlake deponovane vakuum plazma sprej procesom
(Engineering Society for Corrosion, Belgrade, Serbia, 2018)
Tantalum is a very popular material for the industry as a whole because of very important characteristics such as: high melting point, significant thermal and electrical conductivity, high toughness and resistance to ...
