Paper Title:
Microstructure Evolution of the Ti-6.62Al-5.14Sn-1.82Zr Alloy in the Superplastic Compression
  Abstract

Superplastic compression of the Ti-6.62Al-5.14Sn-1.82Zr alloy were carried out at a Thermecmaster-Z simulator at deformation temperatures of 960°C, 980°C, 1000°C and 1020°C, strain rate of 0.001 s-1, 0.01 s-1 and 0.1 s-1, and height reduction of 50%, 60% and 70%. The α phase decreases with the increasing of deformation temperature, and the grain size of α phase has a slight variation with the deformation temperature. The strain rate affects both the morphologies and the grain size of α phase, and the optimal strain rate makes the grains be fine. The optimal height reduction also makes the α phase be fine and well distributed on the matrix of Ti-6.62Al-5.14Sn-1.82Zr alloy after superplastic compression.
