บทคัดย่อ

Mechanical surface treatments (mainly deep rolling) were performed on various steels, such as austenitic stainless steel AISI 304 and normalized plain carbon steel SAE 1045. To evaluate the effectiveness of the mechanical surface treatments, mechanically surface treated specimens were cyclically deformed at room temperature using push-pull stress-controlled fatigue and compared to the non-surfacetreated condition as a reference state. Additionally, the concept, methods and effect of selected mechanical surface treatments will also be addressed in this paper. It was found that mechanical surface treatments can dramatically enhance the fatigue performance of metallic materials as compared to the non-surface-treated condition due to induced near-surface compressive residual stresses, work hardening states and increased near-surface hardnesses inhibiting or retarding surface crack initiation as well as propagation.
