摘要：
The stress-induced martensite transformation in beta solution treated 47Zr-45Ti-5Al-3V alloy was investigated using Gleeble 3500 thermomechanical simulator and D/MAX-2500/PC X-ray diffractometer. Results show that the amount of stress-induced martensite in compressive deformation increases with the decrease of strain rate and initial beta grain size. The triggering stress increases with the increase of strain rate and initial beta grain size, while the ultimate compressive strength decreases. The curve of work-hardening rate vs. true stress can be divided into three stages. The work-hardening rate at stage II or III increases with the decrease of strain rate and initial beta grain size.
