Abstract:The influence of pack ply-rolling process and heat-treatment on the texture characteristics of Ti-6Al-4V alloy sheets was investigated applying the EBSD technique. The tensile properties and fatigue properties of the sheets possessing different type textures were measured. The results show that the alloy sheets possessing single type texture (B or T) exhibit lower fatigue strength compared with the mixed texture (B/T). The sheet possessing basal texture exhibits isotropy and its elastic modulus and yield strength are lower than those under other conditions.
Key words: Ti-6Al-4V alloy; pack ply-rolling; sheet; texture; fatigue properties
