中文摘要:
      本文采用Gleeble 3500热模拟试验机和D/MAX-2500/PC型X射线衍射仪研究了亚稳态β相47Zr-45Ti-5Al-3V合金室温压缩变形过程中的应力诱发马氏体转变行为。结果表明,在压缩变形过程中,应力诱发马氏体的数量随应变速率和初始β相晶粒尺寸的降低而增加。随应变速率和初始β相晶粒尺寸的增加,应力诱发马氏体的触发应力逐渐增加,而抗压强度逐渐降低。加工硬化率随真应力的变化曲线可分为三个阶段,第二和第三阶段的加工硬化率随应变速率和初始β相晶粒尺寸的降低而增加。

英文摘要:
      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.
