RISThe Mechanism of Slip System Activation With Grain Rotation During Superplastic Forming
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The activated slip system of Ti-6Al-4V alloy during the superplastic forming (SPF) was investigated by the in-grain misorientation axes analysis (IGMA), and the mechanisms of slip system activation have been discussed. ...
A 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 ...
