Abstract:
      The stress-induced martensite transformation in β solution treated 47Zr-45Ti-5Al-3V alloy was investigated using Gleeble 3500 thermomechanical simulator and D/MAX-2500/PC X-ray diffractometer. The amount of stress-induced martensite in compressive deformation increased with decreasing strain rate and initial β grain size. The triggering stress increased with increasing strain rate and initial β grain size, while the ultimate compressive strength decreased. The curve of work-hardening rate vs. true stress was divided into three stages. The work-hardening rate at stage ΙΙ or ΙΙΙ increased with decreasing strain rate and initial β grain size.
