| Popis: | This paper is aimed to study the creep behavior of two-phase ultrafine-grained VT8M-1 (Ti-5.7Al-3.8Mo-1.2Zr-1.3Sn) titanium alloy obtained by rotary swaging (RS). It is shown that the 100-hour creep strength of the ultra-fine grained (UFG) VT8M-1 alloy retains high values at temperatures up to 400 °C. An increase in the testing temperature to >450 °C leads to a decrease in the creep rupture strength. The relationship between the microstructure and creep resistance of UFG alloy is discussed. |
