Abstract

Effect of hydrogen on the flow behavior of a TiAl based alloy during plane strain compression at temperatures of 1150 and 1200 °C was investigated in this paper. The results showed that hydrogen obviously softened the alloy and had significant effects on the texture evolution. Hydrogen decreased the number of sharp yield points and hindered the occurrence of Portevin-Le Chatelier effect, which decreased plastic instability of the alloy during plane strain compression. Hydrogen enhanced textures related to γ-phase recrystallization and twinning, as well as α₂-phase pyramidal texture component. Additionally, weak α₂-phase transverse texture component {11–20}<0001> was present in the hydrogenated samples, and the occurrence of such texture was mainly attributed to hydrogen-increased B2 phase.
