Abstract
The present work has been directed towards an understanding of the effect of shot-peening on fatigue properties in terms of the propagation of fatigue cracks through the surface zones of peened samples. Measurements of the residual stress distribution below the surface of peened specimens of a martensitic 12% Cr steel along with results from fatigue crack growth experiments at different mean stresses have been used to determine the relative defect tolerance of peened and untreated fatigue-loaded components. A considerable improvement of up to a factor of 4 can be expected.
Further tests to determine the residual surface stress level after fatigue loading have shown that a reduction can be observed, the extent of which increases with increasing fatigue mean stress and stress amplitude. However, realistic service fatigue stresses cause no significant alteration of the residual stress. Previous observations of a large drop in surface residual stress resulting even in tensile values in peened components may be rationalized in terms of the lower yield strength of the previously investigated steel.
