摘 要:Isothermal compression of a Ti-5.6Al-4.8Sn-2.0Zr alloy was conducted on a Thermecmaster-Z simulator at the deformation temperatures ranging from 960 to 1060°C,the strain rates ranging from 0.001 to 10.0 s-1,and the maximum height reduction of 70.0%.In the two-phase region of the Ti-5.6Al-4.8Sn-2.0Zr alloy,the volume fraction of α phase decreases with an increase in deformation temperature,but the grain size has a slight variation with deformation temperature.The strain rate affects both morphologies and grain size of the α phase in the isothermal compression of the Ti-5.6Al-4.8Sn-2.0Zr alloy.The optimal height reduction also contributes to the small and well-distributed α phase in the isothermal compression of Ti-5.6Al-4.8Sn-2.0Zr alloy.
