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