摘要
研究了汽车用高塑性奥氏体TWIP钢的热变形行为。结果表明,在单向拉伸试验中,随着应变的不断增加应变硬化率先迅速减小,后增加至峰值,最终又开始减小。疲劳加载实验下实验钢开始出现循环硬化,随后表现出稳定、软化特性。
The thermal deformation behavior of the high-plasticity austenitic TWIP steel used ha automotive was investigated. The results show that the strain-hardening rate decreases rapidly firstly and then increases until the peak value and finally decreases again with the increase of the strain during the process of uniaxial tensile. The cyclic hardening appears on the experimental steel and subsequently the stable and softening characteristics occur during the experiment of fatigue loading.
