摘要：

The effects on fatigue crack growth of the application of heat treatment with and without an applied load are discussed. The investigation indicates that when heat treatment is performed simultaneously with an applied load, compressive residual stress will be introduced resulting in better resistance to fatigue crack initiation and growth. Fatigue crack growth tests were performed on single-edge-cracked plates. The fatigue life and crack growth rate for plates with no heat treatment and plates with heat treatment under zero stress are similar. However, for plates with heat treatment carried out under a static load equal to the maximum in the fatigue cycle, the fatigue life increased by 40% and the crack growth rate immediately after heat treatment decreased by 65%. © 1990.
