Microstructure and texture evolution during annealing of Ti�6Al�4V alloy

Abstract

Ti�6Al�4V plates were subjected to warm rolling at 600�C up to 85% reduction in thickness followed by annealing at 850�C for different soak periods. It was observed that the �?� grains were prevalent along the grain boundaries and at the triple junctions of �?� grains. The samples were found to be fully recrystallised after 30 min of annealing time. Further, globularizarion of �?� grains was observed during the progress of annealing. The recrystallisation mechanism was identified to be through sub-grain formation and its growth. A dominant near basal texture, i.e. (Formula presented.) (Formula presented.), was observed in the samples after annealing. � 2020, � 2020 Institute of Materials, Minerals and Mining.
