High temperature materials: properties, demands and applications
(Savez hemijskih inženjera, Beograd, 2020)
High-temperature materials are used in a wide range of industries and applications such as gas turbine engines for aircrafts, power and nuclear power plants, different types of furnaces, including blast furnaces, some fuel ...
Polymer composite films and nanofibers doped with core-shell quantum dots
(Natl Inst Optoelectronics, Bucharest-Magurele, 2020)
Processing and characterization of polymer nanocomposites based on poly(methyl methacrylate) (PMMA) matrix with embedded core-shell CdSe/ZnS quantum dots were investigated. Nanocomposites were obtained via solution casting ...
Friction-stir welding of high-strength aluminium alloys and a numerical simulation of the plunge stage
(Institute of Metals and Technology, 2012)
This paper defines a set of welding parameters for the Friction-Stir Welding (FSW) of two forged panels of the alloy EN AW 7049A in a T652 temper and discusses the plunge stage of FSW using numerical modeling. This ...
A coupled thermo-mechanical model of friction stir welding
(Vinca Institute of Nuclear Sciences, 2012)
A coupled thermo-mechanical model was developed to study the temperature fields, the plunge force and the plastic deformations of Al alloy 2024-T351 under different rotating speed: 350, 400, and 450 rpm, during the friction ...
Cytotoxicity of the gold complex based on mercaptotriazole - A comparison with the conventional cyanide electrolyte
(Journal of the Indian Chemical Society, 2021)
The study presents the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay results on human erythroleukemia K562 cell line to compare the toxicity of electrolytes based on the mercaptotriazole gold ...
Micromechanical analysis of fatigue and crack growth in carbon-fiber epoxy composites based on mechanical testing
(Savez hemijskih inženjera, Beograd, 2020)
The paper presents static and dynamic tests of carbon/epoxy composite materials with fiber orientation at 0 degrees/90 degrees and +/- 45 degrees. The main tensile properties were determined as a basis for subsequent dynamic ...
An analysis of impact testing of high strength low-alloy steels used in ship construction
(Brodogradnja, 2021)
Brittle damages have been examined widely since welding became common practice when it comes to carrying out robust structures. Welded structure of the ship hull has to be continuous. Brittle damages that occur on hull ...
