Abstract

Abstract: The compressive true stress vs.true strain curves of Ti-10V-2Fe-3Al alloy have been measured in β phase region at 850℃~950℃×10-ss-1~10s-1.The results show that the soft mechanism is mainly dynamic recovery when the specimen is deformed in the range of T = 850℃~950℃ and e = 10-1s-1~10s-1, the -e curves show the shape of the dynamic recovery and the deformed grain is lengthened. The mathematical model of flow stress has been proposed on the basis of mathematical analysis.

Key words: titanium alloy, flow stress, dynamic recovery, stress exponent.
