Stress controlled fatigue-creep behavior of 316L stainless steel under different temperatures

摘要：

Stress controlled fatigue-creep tests were carried out for 316L stainless steel at different temperatures which are just in the dynamic strain aging regime of this material. Dynamic strain aging was found to manifest itself macroscopically as displacement or mean strain abrupt jumps during cyclic deformation. At higher temperature (560℃,575℃),abrupt displacement jumps occur at the early stage of cyclic deformation and there are many jumps during the whole process. While at lower temperature (540℃),displacement only jumps once at the end of deformation.
