| 摘 要： | 对316L不锈钢进行了大量的单轴高周次棘轮和蠕变试验，讨论了在长达20 000周应力循环中材料的棘轮变形演化与饱和棘轮变形的规律，以及棘轮幅值应力对峰值控制规律的影响；基于材料棘轮效应和蠕变迁为之间相互联系的系统研究提示出：材料的棘轮变形本质上源于应力循环过程中材料的黏塑性。

| Abstract: | A series of uniaxial ratchet and creep tests on 316L stainless steel were performed. in the 20 000 stress cycles, the evolution rule of ratchet deformation and the propirty of saturated ratchet strain of this material were discussed. And the phenomenon that the amplitude stress affects the peak-stress-dominating-rule was investigated. The results from research on the relationship between ratchet and creep behavior of the material show htat the ratchet deformation under cyclic stressing is essentially caused by visc-plastic of the material. |
