Effect of processing parameters on hot deformation behavior and microstructural evolution during hot compression of Ti40 titanium alloy

Effects of the processing parameters on the flow stress behavior and the microstructural revolution are investigated in the hot compression of Ti40 alloy. The experimental results show that the flow softening occurring at high strain rate, is associated with deformation heating, flow instability, cr...

Zusammenfassung:	Effects of the processing parameters on the flow stress behavior and the microstructural revolution are investigated in the hot compression of Ti40 alloy. The experimental results show that the flow softening occurring at high strain rate, is associated with deformation heating, flow instability, cracking and DRX, while that occurring at low strain rate is contributed to DR and DRX. Effects of processing parameters on microstructural revolution are analyzed. At low temperature (
