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 ...
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, ...
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 ...
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 ...
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 ...
Problems and prospect of Al-Mg alloys application in marine constructions
(Savez inženjera metalurgije Srbije, Beograd, 2006)
The position of steel as the most widely used material in the shipbuilding industry originates from the superior mechanical properties and low manufacturing costs The increasing demands for lowering the weight of different ...
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 ...
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 ...
