Abstract:

Two low alloy steels, heat treated to yield strengths approximating 175,000 and 150,000 psi, were fatigue tested under rotating beam conditions at temperatures of 70, 400, 600, 800 and 1000 F. The fatigue data is related to the tensile properties at various test temperatures. Temper embrittlement, occurring during the course of fatigue testing and its effect on the fatigue properties, is also demonstrated. For the steels investigated, the elevated temperature tensile properties appear to be good predictors of elevated temperature fatigue behavior. However, the occurrence of a subcritical temperature phenomenon to which the specific steel is susceptible such as temper embrittlement will affect the fatigue behavior and destroy its fatigue-tensile relationship.
