Shot-peening induced twinning in ship-building steel / Dvojnikovanje u brodskom limu kao posledica tretiranja u mlazu sačme
(Savez inženjera metalurgije Srbije, Beograd, 2002)
The aim of this work to simulate a shot-peening process and reveal the final microstructure. The latter consisted of rafinated ferritic grains, with occurrence of twins in some grains. Since the twinning occurs when a very ...
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 ...
Hydrometallurgical process for extraction of metals from electronic waste, Part I: Material characterization and process option selection
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Used electronic equipment became one of the fastest growing waste streams in the world. In the past two decades recycling of printed circuit boards (PCBs) has been based on pyrometallurgy, highly polluting recycling ...
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, ...
Application of instrumental methods in the investigation of properties and microstructure of construction concretes / Primena instrumentalnih metoda za ispitivanje svojstava i mikrostrukture konstukcionih betona
(Savez inženjera metalurgije Srbije, Beograd, 2008)
Methods for the investigation of microstructure of construction concretes are presented in this paper. Concrete is a composite material, thus its microstructure consists of bonding agent (cement) and aggregate with predefined ...
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 ...
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 ...
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 ...
