Characterization of nano-powder morphology obtained by ultrasonic spray pyrolysis
(Savez inženjera metalurgije Srbije, Beograd, 2008)
Spherical nanosized particles of copper were synthesized by ultrasonic dispersion of solutions from copper sulphate in the temperature range of 800-900°C in hydrogen atmosphere. A controlled particle size was realized ...
Determination of AL2O3particle size in Cu-AL2O3 nanocomposite materials using UV spectrophotometry / Određivanje veličine čestica AL2O3 u nanokompozitnim materijalima iz sistema Cu-AL2O3 primenom UV spektrofotometrije
(Savez inženjera metalurgije Srbije, Beograd, 2008)
In order to achieve improved mechanical properties of dispersion strengthened nanocomposite, without influencing electrical and thermal conductivity it is necessary for dispersoide to be nano sized and uniformly distributed ...
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 ...
On the Al-Mg alloy sheets for automotive application: Problems and solutions
(Savez inženjera metalurgije Srbije, Beograd, 2004)
Aluminium alloys suitable for automotive application were reviewed briefly as well as the reasons for the future wider application of Al-Mg type alloys. Basic problems related to the limited consumption of Al-Mg type alloy ...
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 ...
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 ...
