| 摘 要： | 由于变形过程中产生应变诱发马氏体相变，亚稳奥氏体不锈钢低温下硬化曲线呈S形。在每隔1．5％的工程应变小区间利用Hollomon公式求得硬化指数n，发现n值不是常数。而且n值和硬化率随应变的增加呈抛物线形变化，n值随着应变率的增高相应的减小。

| Abstract: | The hardening curve exhibits sigmoid shape in metastable austenite stainless steel at low temperature due to strain induced martensite transformation during deformation. The hardening exponent n values derived from Hollomon equation in each 1 5% of nominal strain are found not to be constant. Furthermore, both the n values and the hardening rate present parabola with increase of strain, while n values decrease correspondingly with increase of strain rate. |
