We have investigated the superplastic deformation mechanism of a powder-metallurgy, high-zinc X7093 Al alloy. The objective was to examine the rate-controlling mechanisms that govern its superplastic deformation. The investigations were carried out in the temperature range 490–524 °C and strain rate ...

Ti3Al-11Nb-1V (x/%) was made in a vacuum arc furnace. Hot-rolling was conducted at 1050 °C in a two-phase field of the alloy. Strain-rate jump tests were performed at T = 800-1100 °C and strain rates of 10-6 to 10-3 s-1. Creep stress exponent (n) and activation energy for deformation (Q) were used t ...
