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 ...
Fabrication of high strength seam welded steel tubes and quality indicator testing / Izrada šavnih cevi od čelika povišene čvrstoće i ispitivanje pokazatelja kvaliteta
(Society for Structural Integrity and Life, Institute for Material Testing, 2008)
The selection of steel, the dimensions and methods of fabricating seam welded steel tubes are closely connected to the function of tube as a whole structure in specific working conditions, for a calculated service life. ...
Integrity of biomedical implants of titanium alloys: Second part / Integritet biomedicinskih implanta od legura titana - drugi deo
(Society for Structural Integrity and Life, Institute for Material Testing, 2008)
This article reviews the diverse metallic materials for biomedical engineering applications and it is shown that titanium and titanium alloys possess numerous advantages, compared with other biocompatible metallic materials ...
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 ...
Application of the residual strength degradation model to carbon-epoxy composite
(Consultants Bureau/Springer, New York, 2008)
A residual strength degradation model for two orientations of fibers of carbon-epoxy composite is proposed. The model is constructed on the basis of an analysis of a gradual decrease in the residual strength of the composite ...
Morphologies of electrochemically formed copper powder particles and their dependence on the quantity of evolved hydrogen
(Elsevier Science Sa, Lausanne, 2008)
Copper powder particles formed by electrolysis under different quantities of evolved hydrogen were analyzed using the scanning electron microscopy (SEM) technique. It was found that the structure of the powder particles ...
