Abstract

Hydrogen effect on the deformation behaviour of the ultrafine-grained titanium alloy (VT16 grade) is studied at the temperature interval (293–973) K. Hydrogenation to the concentration of 0.3 wt % is found to lead to an increase in the values of uniform deformation and total deformation to failure at temperatures 293–573 K. In the range of higher temperatures (673–973) K, hydrogen presence reduces the resistance of the ultrafine-grained VT16 alloy to the localization of deformation at the macro-level and value of deformation to failure. Possible reasons for the increase in the transition temperature of the ultrafine-grained VT16 alloy to the superplastic state and the decrease in the temperature interval of the manifestation of its superplastic properties in the presence of hydrogen in a solid solution are discussed.

Abstract

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. [ABSTRACT FROM AUTHOR]
