Effect of annealing on creep of titanium VT16 alloy in the ultrafine-grained state

Effect of annealing at temperature below recrystallization temperature on creep of the ultrafine-grained (α + β) titanium VT16 alloy at temperature of 723 K and rate interval of 10−6–10−5 s−1 is studied. Preliminary annealing of the ultrafine-grained VT16 alloy at temperature of 673 K for 6–30 hours...

Zusammenfassung:Effect of annealing at temperature below recrystallization temperature on creep of the ultrafine-grained (α + β) titanium VT16 alloy at temperature of 723 K and rate interval of 10−6–10−5 s−1 is studied. Preliminary annealing of the ultrafine-grained VT16 alloy at temperature of 673 K for 6–30 hours is found to result in decrease of steady-state creep rate and increase in deformation value and time to failure. Possible reasons of increase in creep resistance of VT16 alloy after prerecrystallization annealing are discussed.
