RISA Modified Constitutive Model With Grain Rotation for Superplastic Forming of Ti–6Al–4V Alloy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A physically based constitutive model with internal state variables (ISVs) is established, it is used to describe the flow stress and microstructure evolution of Ti–6Al–4V alloy in the superplastic forming (SPF). The ISVs ...
