摘要：

The nature of arrested cracks in run-out fatigue tests of a type 316L austenitic stainless steel with electropolished surfaces has been investigated. The fatigue limit was determined in rotating-bending by means of the staircase method to be 302 +/- 5 MPa. Arrested crack nuclei were shown to arrest at coherent deformation twins, developed by fatigue.
