(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2007)
Korišćenjem metoda optičke mikroskopije, kvantitativne optičke mikroskopije SEM i EDS analize izvršena su ispitivanja strukture, kao i analiza faznog i hemijskog sastava, kod trenjem zavarenih spojeva brzoreznog čelika Č ...
Static and impact crack properties of a high-strength steel welded joint
(Elsevier Sci Ltd, Oxford, 2007)
in order to gain the benefits of weldable high-strength steels in pressurized equipment applications, satisfactory toughness and crack properties of the welded joint, both in the weld metal and the heat-affected-zone (HAZ), ...
Influence of Si content and cooling rates on the size of SDAS and the latent heat released in Al-Si(5-11)-Cu1 alloys
(Proceedings - European Metallurgical Conference, EMC 2007, 2007)
The latent heat of solidification of any alloy depends on the chemistry and the microstructure developed during solidification process. Effects of chemistry on the release of the latent heat during solidification and ...
Sulphur concrete
(Structural Engineering Conferences, SECON, 2007)
Sulphur concrete is a relatively new material, and although similar in final appearance to portland cement concrete, its manufacture, handling, use, and testing are different. Sulphur concrete is a thermoplastic material ...
Uticaj otkaza zubaca na bezbednost mašina - ispitivanje i analiza / The effect of teeth failures on machine safety: Testing and analysis
(Institut za ispitivanje materijala, Beograd, 2007)
Odredbama Mašinske direktive 98/37/EC definisani su osnovni zahtevi koje moraju da ispune zupčasti prenosnici snage u pogledu zdravstvene i bezbednosne zaštite. U radu su opisani različiti oblici oštećenja i razaranja ...
Klasifikacija eksploatacijskih oštećenja čeličnih užadi / Classification of in-service damages of Steel wire ropes
(Institut za ispitivanje materijala, Beograd, 2007)
Radni vek čeličnih užadi je ograničen zbog promene njihovih svojstava tokom eksploatacije pod dejstvom radnih uslova i opterećenja. Redovan nadzor tokom eksploatacije omogućava kontrolu razvoja oštećenja i normalni proces ...
Neka svojstva peno-betona
(Univerzitet u Nišu - Građevinsko-arhitektonski fakultet, Niš, 2007)
U svetskoj praksi primena peno - betona je veoma raširena, naročito za prekrivanje i termičku izolaciju industrijskih i komercijalnih zgrada. Ovim projektom hteli smo da približimo građevinskoj javnosti mogućnosti primene ...
