Uticaj različitih faktora na pojavu acikularne feritne strukture u metalu šava / The influence of different factors on appearance of accicular ferrite structure in weld metal
(Kriminalističko-policijski univerzitet, Beograd, 1999)
U ovom radu biće razmatran zavareni spoj (metal šava) kao deo koji spaja segmente konstrukcije i kod čelika može biti vrlo kritično mesto. Mehaničke osobine i udarna žilavost zavarenog spoja zavise prvenstveno od mikrostrukture ...
Study of the simulated heat affected zone of creep resistant 9-12% advanced chromium steel
(Taylor & Francis Inc, Philadelphia, 2008)
Global warming leads to research-development attempts worldwide with a view to reduce CO2 emission. Therefore, in the energy supply sector, a special focus has been directed to further development of steels that can endure ...
Transition temperature and fracture mode of as-castand austempered ductile iron
(Wiley, Hoboken, 2008)
The ductile to brittle transition temperature is a very important criterion that is used for selection of materials in some applications, especially in low-temperature conditions. For that reason, in this paper transition ...
The austempering study of alloyed ductile iron
(Elsevier Sci Ltd, Oxford, 2006)
Austempered ductile iron (ADI) proved to be an excellent material as it possesses attractive properties: high strength, ductility and toughness are combined with good wear resistance and machinability. These properties can ...
Optimisation of the deposition parameters of thick atmospheric plasma spray coatings
(Journal of the Balkan Tribological Association, 2012)
Plasma spray process is one of the most versatile thermal spray deposition processes. There are great number of parameters that influence the quality and characteristic of deposited coating and their values must be defined ...
Corrosion behavior of the as-cast and heat-treated ZA27 alloy
(Fakultet inženjerskih nauka, Kragujevac, 2011)
Corrosion behaviour of the as-cast and heat-treated ZA27 alloy was examined. The alloy was prepared by conventional melting and casting route and then thermally processed by applying T4 heat treatment regime (solutionizing ...
Određivanje vremenske čvrstoće pomoću mikrostrukturnih parametara niskolegiranih čelika izloženih puzanju - drugi deo - određivanje vremena do loma / Estimation of long-term strength by microstructural parameters of low-alloyed steel exposed to creep: Second part: Determination of time-to-fracture
(Institut za ispitivanje materijala, Beograd, 2003)
Mikrostrukturni parametri, dobijeni na osnovu kinetičke teorije čvrstoće (model Žurkova) su korišćeni za određivanje vremena do loma materijala izloženog puzanju na visokoj temperaturi. Ulazni parametar, potreban za ...
Acikularni ferit u metalu šava niskougljeničnih čelika / Acicular ferrite in weld metal of low carbon steel
(Institut za ispitivanje materijala, Beograd, 2005)
Ustanovljeno je da u metalu šava mikrolegiranih čelika dominira struktura ferita, koja se javlja u različitim morfološkim oblicima. Koji ce od njih biti najzastupljeniji u mikrostrukturi metala šava zavisi od velikog broja ...
Određivanje vremenske čvrstoće pomoću mikrostrukturnih parametara niskolegiranih čelika izloženih puzanju - prvi deo / Estimation of long-term strength by microstructural parameters of low-alloyed steel exposed to creep: First part
(Institut za ispitivanje materijala, Beograd, 2003)
Prikazan je statistički regresioni model određivanja trajne čvrstoće materijala dugotrajno izloženog visokotemperaturskom puzanju pomoću parametara mikrostrukture. Parametri mikrostrukture su dobijeni na osnovu kinetičke ...
Low temperature sintering of mechanically activated BaCO3-TiO2
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2002)
U ovome radu je proučavano niskotemperaturno sinterovanje mehanički aktiviranog sistema BaCO3-TiO2. Prah BaCO3 i TiO2 u stehiometrijskom odnosu je mehanički aktiviran u visokoenergetskom vibracionom mlinu tokom 0, 30, 90 ...
