• 論文の詳細を見る

• The rotating bending fatigue properties of normal shot-peened(SP)and hard shot-peened(HSP)316L austenitic stainless steels were investigated from the viewpoints of the changes of hardness distribution and compressive residual stress distribution during the high-cycle fatigue test. The investigation of the crack growth behavior was also carried out using a replication technique. It was found that the fatigue strength was improved by shot-peening treatments, and the fatigue crack propagation mechanisms were clarified in the SP and HSP specimens. The fatigue crack growth behavior in the SP and HSP specimens was completely different from that of the non-peened specimens. The differences were caused by the change of the hardness distributions and the residual stress distributions during the fatigue test.
