Experimental and numerical thermo - mechanical analysis of friction stir welding of high - strength alluminium alloy
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
This paper presents experimental and numerical analysis of the change of temperature and force in the vertical direction during the friction stir welding of high-strength aluminium alloy 2024 T3. This procedure confirmed ...
Influence of friction stir welding parameters on properties of 2024 t3 aluminium alloy joints
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The aim of this work is to analyse the process of friction stir welding (FSW) of 3 mm thick aluminium plates made of high strength aluminium alloy - 2024 T3, as well as to assess the mechanical properties of the produced ...
Hydrometallurgical recovery of tin and lead from waste printed circuit boards (wpcbs): limitations and opportunities
(Croatian Metallurgical Soc, Zagreb, 2016)
In this paper, possibility for selective Pb and Sn recovery, using three different solutions of NaOH, HCl and HNO3, from WPCBs containing low concentrations of Pb and Sn is presented. According to obtained results, over ...
Heat generation during plunge stage in friction stir welding
(Vinca Institute of Nuclear Sciences, 2013)
This paper deals with the heat generation in the Al alloy Al2024-T3 plate under different rotating speeds and plunge speeds during the plunge stage of friction stir welding. A 3-D finite element model is developed in the ...
Advantage of use of activated flux-cored wire instead of solid wire with the mag welding process from the mechanical properties aspect
(Croatian Metallurgical Soc, Zagreb, 2013)
The objective of this paper is the analysis and evaluation of the quality of the new flux-cored wire designed for the MAG welding process that was developed and produced using special laboratory equipment. Experimental ...
Functional, rheological and sensory properties of probiotic milk chocolate produced in a ball mill
(Royal Soc Chemistry, Cambridge, 2016)
The aim of this study was to investigate the survival of probiotics (Lactobacillus acidophilus NCFM, Lactobacillus rhamnosus HN001 and Bifidobacterium lactis HN019) in milk chocolate masses prepared at temperatures 35 ...
Novel β-galactosidase nanobiocatalyst systems for application in the synthesis of bioactive galactosides
(Royal Society of Chemistry, 2016)
In this study, unmodified, amino modified and cyanuric chloride functionalized amino modified nonporous fumed nano-silica particles (FNS, AFNS and CCAFNS, respectively) were used for the development of efficient nanobiocatalysts ...
Comparison of Mechanical Behavior of SiC Sintered Specimen to Analysis of Surface Defects
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2014)
Silicon carbide is the material that in sintered form is suiTab. for protection from impact as part of the multilayered structure. Its role is to accumulate energy from the projectile, to plastically deform the projectile ...
