摘要：

The fatigue-creep behaviors of hot rolled and dynamic strain aging pre-treated 316L austenitic stainless steels were investigated under different loading conditions at 550 degrees C. Under stress control mode, the macroscopic manifestation of dynamic strain aging is the abrupt displacement jumps during cyclic deformation. By comparing with the hot rolled treatment the dynamic strain aging pre-treatment makes the cyclic strain amplitude decrease and the cycle number at the first abrupt displacement jump postpone, i.e., the material strength is enhanced and fatigue-creep life is effectively prolonged.
