摘要:
AbstractThe tensile and bulging characteristics of Ti–6Al–4V alloy sheet have been investigated under superplastic conditions following various prior treatments. These prior treatments. consisted of cold rolling to different degrees of reduction and recrystallization. It was found that cold rolling markedly improves the superplasticity of the alloy, and even recrystallization, which causes grain coarsening, does not eliminate this effect. Moreover, the ratio of the total tensile elongation to the bulging strain to failure was found to decrease with increased prerolling.MST/172
