Abstract
This paper discusses cyclic deformation and fatigue behavior of three grades of stainless steel 304L. Effects of pre-straining and mean stress were investigated and it was observed that these parameters influence both deformation and fatigue behaviors. At HCF, significant secondary hardening was observed for two of the materials, leading to a significant change in fatigue behavior at long lives. For two of the materials, pre-strained tests were also conducted. Hardening was observed as a consequence of pre-straining and affected further deformation and fatigue behaviors significantly. Mean stress effects on fatigue lives were as expected, as compressive mean stress lengthened life and tensile mean stress shortened life. The Smith-Watson-Topper (SWT) parameter was used to correlate the experimental data from all test conditions for the three materials and was found to correlate the experimental data reasonably well.
