The austenitic stainless steel AISI 304 was deep rolled at 20 °C (RTDR), -195 °C (CTDR), and 550 °C (HTDR). The deep rolling pressures used for each deep rolling temperature were 1.0, 1.7, and 2.4 bar. From microstructural investigation, the largest compressive residual stress field was found in RTDR, and the highest amount of martensitic content and plastic deformation were found in CTDR. The strain aging effect was only found in HTDR. In the rotating bending fatigue tests, the strain aging effect after HTDR is ...
