The contradiction matrix is the most popular tool of the Theory of Inventive Problem Solving (TIPS, rus. TRIZ). It consists of 39 engineering parameters and 40 principles. Intersecting a parameter that is improving with ...
Production of sub-micro sized silver particles by chemical reduction method in an environmentally-friendly manner
(Savez inženjera metalurgije Srbije, Beograd, 2020)
Silver nitrate in the solution was reduced in the presence of the dispersants by ascorbic acid, and silver particles were generated. The main goal was to examine the influence of different dispersants. The purpose was to ...
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 ...
INTEGRITY AND RISK ASSESSMENT OF RECONSTRUCTED STEAM LINE / PROCENA INTEGRITETA I RIZIKA REKONSTRUISANOG PAROVODA
(Society for Structural Integrity and Life (DIVK), 2023)
The integrity assessment of high pressure steam pipeline
primarily requires stress state determination, including not
only effects of working pressure and temperature, but also
all acting loads. Toward this aim, the ...
