Radionuclide Immobilization by Sorption onto Waste Concrete and Bricks-Experimental Design Methodology
(Springer International Publishing Ag, Cham, 2019)
The utilization of construction and demolition waste materials for the radionuclide immobilization by sorption processes was investigated. Given that the liquid radioactive waste usually has a complex composition and that ...
The Effect of Vanadium Content on Microstructure and Impact Toughness of Forged High Alloy Steel X96CrMo12-1
(Springer International Publishing Ag, Cham, 2019)
The aim of this research was to examine the influence of vanadium on the structure and impact toughness of the forged high alloy steel X96CrMo12-1. It is known that vanadium affects the process of solidification of this ...
Cavitation Wear of Basalt-Based Glass Ceramic
(MDPI, Basel, 2019)
This paper examines the possibility of using basalt-based glass ceramics for construction of structural parts of equipment in metallurgy and mining. An ultrasonic vibration method with a stationary sample pursuant to the ...
Creep crack growth behavior of p91 steel weldments
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
The steels operating at elevated temperatures are well known to be exposed to premature failure due to cracking caused by constant thermal stress, i. e. secondary creep process. Therefore, creep crack growth tests were ...
Parametric optimization of the aluminium nanocomposites wear rate
(Springer Heidelberg, Heidelberg, 2019)
The optimization of wear rate of the nanocomposites with A356 aluminium alloy matrix, reinforced with silicon carbide nanoparticles, was performed through the analysis of the following influences: wt% of the reinforcement, ...
Experimental and numerical analysis of thermo-chemical erosion in gun steel
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
Various factors of thermo-chemical erosion process in gun steel were analysed. The factors are mainly related to the thermal load of gun barrel inside surface, characteristics of barrel surface and chemical interactions ...
The Mechanisms of Cavitation Erosion of Raw and Sintered Basalt
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2019)
The paper analyzes the morphology of cavitation damage of raw and sintered basalt samples. The experiment was conducted using the ultrasonic vibratory cavitation test method according to the ASTM G-32 standard. During the ...
Temperature fields in linear stage of friction stir welding effect of different material properties
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
Friction stir welding is one of the procedures for joining the parts in solid state. Thermo-mechanical simulation of the friction stir welding of high-strength aluminium alloys 2024 T3 and 2024 T351 is considered in this ...
