Loss of coherency at interphase α/β boundary in Ti-6Al-4V alloys during deformation at 800°C

Abstract

Ti-6Al-4V is one of the major titanium-based alloy especially for creep purposes. The alloy is generally subjected to high temperature deformation and it is generally used at warm/high temperatures. The alloy (α+β→β)-transus temperature is 995°C, that is, for temperatures within 995°C a mixed α+β phases microstructure characterizes the alloy mechanical behavior
