An improved method for thermal stability behavior characterization of silicon carbide/cordierite composite material
(Savez inženjera metalurgije Srbije, Beograd, 2007)
In the present work Mg-exchanged zeolit and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 50:50. Samples were exposed to the water quench test from 950°C, ...
Kinetics of crystallization silicon-(IV)-nitride / Kinetika kristalizacije silicijum-(IV)-nitrida
(Savez inženjera metalurgije Srbije, Beograd, 2003)
Amorphous covalent Si-C-N ceramics have been synthesized by pyrolysis polysilazanes. This part of experiment was done in Institute für Nichtmetallische Anorganische Materialien, Universitaet Stuttgart, Germany. Ceramics ...
Development of a collision energy absorber of a passenger train
(Savez inženjera metalurgije Srbije, Beograd, 2007)
Development of shock absorbers is one of the necessary measures for passive protection of passenger coaches. The purpose of passive protection is to minimize the collision consequences for passengers. Present solutions are ...
Determination of activation energy for static recrystallization using multipass continuous cooling torsion test
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Two microalloyed steels (Nb low carbon and V medium carbon) were tested by means of multistage continuous cooling torsion with aim to evaluate the interpass recrystallization data, by means of Tnr (temperature of ...
Deformation behavior of the AlMg4.5Cu0.5 type alloy sheet
(Savez inženjera metalurgije Srbije, Beograd, 2005)
Deformation behavior of the AlMg4.5Cu0.5 type alloy sheets was examined after cold rolling and annealing in the range of temperature from 220°C to 520°C, water quenching and natural aging. The low temperature annealed ...
The effect of heat treatment on toughness and wear resistance of Fe-Cr-C-Nb alloys / Uticaj termičke obrade na žilavost i otpornost na habanje Fe-Cr-C-Nb legura
(Savez inženjera metalurgije Srbije, Beograd, 2008)
Alloying with niobium improves the mechanical properties of the high chromium irons. The alloy containing appriximately 3 %Nb gives the best compromise between wear resistance and toughness. These properties were improved ...
Structural characteristics of some ternary Ag-In-Sn alloys
(Savez inženjera metalurgije Srbije, Beograd, 2008)
The Ag-In-Sn system, as one of potential lead-free solder materials, was studied in this paper. The investigated alloys were chosen from two sections, with molar ratio of In:Sn equal to 1:4; 1:2. DTA, XRD, SEM and micro ...
