Research on the hot deformation behavior of Ti40 alloy using processing map

▶ The tests were conducted at the temperature between 900 and 1100 °C and strain rates between 0.01 and 10 s−1. ▶ Hot deformation activation energy of the Ti40 alloy was calculated. ▶ The constitutive equation of Ti40 alloy was developed based on Arrhenius kinetic rate equation. ▶ The processing maps at strain of 0.5 and 0.6 were generated, respectively.▶ The evidence of deformation in stability and instability domains has been identified by the microstructure observations of Ti40 titanium alloy.
