摘要
The damaging effects of small defects introduced by processing, fabrication and in-service operation on the fatigue properties of low alloy steels have been studied in relation to residual stress fields. The diverse roles played by inclusions, corrosion pits, fretting damage and where appropriate, their associated residual stress fields are each considered. The observed effects are discussed in relation to both S-N data and fracture mechanics and fatigue crack growth threshold concepts.
