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 ...
The influence of the cellular structure of the seed on the structure single crystal superalloy based on Ni / Uticaj ćelijske strukture klice na strukturu monokristala superlegure na bazi Ni
(Savez inženjera metalurgije Srbije, Beograd, 2003)
This paper elaborates the investigations about influence of the cellular structure of the seed to the distance between primary dendrites, λ1 Investigations were performed on superalloy single crystals based Ni which were ...
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, ...
The effect of mould temperature and cooling conditions on the size of secondary dendrite arm spacing in Al-7Si-3Cu alloy
(Savez inženjera metalurgije Srbije, Beograd, 2009)
The secondary dendrite arm spacing (SDAS) is one of the most important microstructure features of as-cast structure in hypoeutectic aluminum alloys. The size of SDAS depends on many factors such as liquid metal treatment, ...
Monitoring the damage level during thermal stability testing of refractory sample using soninic measurement
(Savez inženjera metalurgije Srbije, Beograd, 2002)
Thermal stability of the refractory material with the content of 28 % AI2O3 was investigated. Water quench test (JUS.B.D8.319.) was applied as experimental method for thermal stability testing. Dynamic Young modulus of ...
Approximation of material behaviour of PLLA polymer in HAp/PLLA biocomposite material using nanoindentation and finite element method
(Savez inženjera metalurgije Srbije, Beograd, 2007)
In this work, a combination of nanoindentation experiment and finite element modeling is proposed in order to obtain approximate material behavior of PLLA polymer in hydroxyapatite (HAp)/poly-L-lactide (PLLA) composite. ...
Rotating disk alumina precursor fiber formation process stability determination using image analysis
(Savez inženjera metalurgije Srbije, Beograd, 2002)
Precursor fibers are made from the aluminium-hydroxide chloride based sols. The process stability can be influenced both by the fiber formation conditions and the rheology of the sol. The distance from the disk canter is ...
Influence of vanadium content and colling rate on the stereological parameters of phases in the structure of Fe-C-Cr-V alloys / Uticaj sadržaja vanadijuma i brzine hlađenja na stereološke parametre faza u strukturi Fe-C-Cr-V legura
(Savez inženjera metalurgije Srbije, Beograd, 2004)
In this paper, the influence of vanadium content and cooling rate on the stereological parameters of phases present in the structure of Fe-C-Cr-V alloys. Experimental results indicate that both vanadium content and cooling ...
