Abstract

Isothermal compression of Ti-5.6Al-4.8Sn-2.0Zr alloy was carried out on a Thermecmaster-Z simulator at deformation temperatures between 960 and 1060 °C, constant strain rate between 0.001 and 10.0 s^-1, and a maximum height reduction of 70%. The high temperature deformation behavior of Ti-5.6Al-4.8Sn-2.0Zr was characterized based on an analysis of the stress-strain behavior, kinetics and processing map. The activation energy for deformation obtained during high temperature compression of Ti-5.6Al-4.8Sn-2.0Zr alloy are 221.7 kJ/mol in the β phase region and 1082.4 kJ/mol in the α + β phase region. The constitutive equation proposed to describe the flow stress as a function of strain rate, strain and deformation temperature during high temperature compression of Ti-5.6Al-4.8Sn-2.0Zr alloy enables a close agreement between the predicted and experimental stress-strain curves.
