Utjecaj temperature na mehanička svojstva slitina niobija u sustavu Nb-W-Mo-Zr

Data obtained for the short-term strength and ductility of thin sheet, weld metal, and welded joints of niobium alloys 5VMTs and 10VMTs of the system Nb-W-Mo-Zr in the temperature range 290 - 2 270 K are analyzed. The structure, deformation mechanisms governing plastic deformation, and the nature of alloy failure in the temperature range are determined.Analizirani su podaci dobiveni za kratkoročnu čvrstoću i plastičnost tankog lima, zavarnog metala, zavarenih spojeva slitina niobija 5VMTs i 10VMTs u sistemu Nb-W-Mo-Zr u području temperature od 290 - 2 270 K. Određeni su mehanizmi stru-kture deformacije koji upravljaju plastičnom deformacijom i priroda grešaka u slitini u tom području temperature
