Abstract:
??????The Ti–6Al–4V alloy were thermo-forged in α+β two phase region,and then recrystallized in three different temperatures. The results show that the initial microstructure were fully transformed into fine equiaxed α and lamellar α+β,the fine equiaxed α and lamellar α+βwere gradually coarsening as increasing recrystallization temperature,the relative frequency of recrystallization grain were also increased,low angle boundary shows a converse trend. The total elongation and area reduction reach up to 19.9% and 42.5%,the mechanical properties gradually decreased as the elevate temperature which were attribute to coarse and inhomogeneous grain.
