“…However, it must be remarked that although surface microgeometry, hardness and residual stress are recognized to have a primary role in fatigue behaviour [244,245], no general model exists to describe the effects of surface preparation [84,139].…”

Precipitation-hardened stainless steel of 15-5PH grade was used for the fabrication of forward cylinder used in advanced linear actuator of aircraft. The component had undergone a series of qualification tests. During one of the accelerated fatigue tests, an external leak was observed after experiencing more than 1,50,000 cycles of fluctuating stress. Subsequent to disassembly, the leak was found to be because of the hair line cracks in the forward cylinder. The cracked component was subjected to a detailed metallurgical investigation to understand the cause of failure. The failure analysis revealed that the fracture initiated at the hard chrome layer and propagated under cyclic loading. This premature failure of the component was attributed to the surface roughness and the presence of the hard chrome layer at the corner contour of the component. This article brings out the details of the investigation carried out and the results achieved.Keywords 15-5PH stainless steel Á Hard chrome layer Á Effect of surface roughness on fatigue Á Fatigue failure

“…The fatigue limit is known to be sensitive to the surface characteristics of roughness, hardness and residual stress (Yahata et al, 1982;Yahata, 1987). However, there is no general model or description for the effects of surface preparation on the fatigue behaviour, in particular for austenitic stainless steels.…”
