Abstract4onstant amplitude and spectrum loading fatigue crack growth rate tests were performed on HP-9Ni4X+3OC steel heat treated to three strength levels. It was concluded that the constant nmplltude crack growth rate is dependent on the stxenath level of the material and independent of the toughne
A modification to the model of Weir ef al. for surface reaction and transport controlled fatigue crack growth has been developed to explicitly account for the effect of load ratio on environmentally assisted fatigue crack growth. Load ratio was found to affect principalfy gas transport to the crack
