Investigation of dynamic young modulus during thermal stability testing of the refractory material / Određivanje dinamičkog jungovog modula elastičnosti tokom ispitivanja termostabilnosti vatrostalnog materijala
(Savez inženjera metalurgije Srbije, Beograd, 2002)
Thermal stability of the refractory material with the content of 42 % Al2O3 was investigated. Water quench test (JUS.B.D8.319.) was applied. Photographs of the samples before cycling, and after some number of cycles were ...
Laboratory investigation of cavitation resistance of materials: Modified ultrasonically induced cavitation test method / Laboratorijsko istraživanje kavitacione otpornosti materijala - modificirana ultrazvučna metoda
(Savez inženjera metalurgije Srbije, Beograd, 2008)
Cavitation erosion represents an actual problem in machines, whose components such as propellers, blades of hydraulic pumps and turbines, are exposed to high-speed flow of liquid. Research exhibited that hydraulic machinery ...
Structure and kinetics of internal oxidation in Ag-Sn alloys / Struktura i kinetika interne oksidacije Ag-Sn legura
(Savez inženjera metalurgije Srbije, Beograd, 2008)
Internal oxidation in Ag-Sn-In-Te and Ag-Sn-Cu-Bi alloys was tested. micro structures of casted and homogenized samples, as well as after internal oxidation were followed by optical microscopy. The structure of Ag-Sn-Cu-Bi ...
The effects of thermomechanical treatment on the SCC resistance of highly alloyed Al-Mg sheet / Uticaj termomehaničke obrade na otpornost prema naponskoj koroziji visoko legiranih Al-Mg limova
(Savez inženjera metalurgije Srbije, Beograd, 2002)
The effects of cold work and different heat treatments on the stress corrosion cracking (SCC) behavior of Al-Mg6.8% alloy were studied using slow strain rate testing (SSRT). The results have indicated high SCC susceptibility ...
