Effect of thermal and mechanical loadings on the residual stress field in a nickel based superalloy using X-ray Laue microdiffraction

Résumé

The shot-peening operation is used to improve the fatigue lifetime of mechanical components through the introduction of compressive residual stresses and plastic deformation in a surface layer. In this study, the Laue microdiffraction technique is used to investigate deviatoric strain fields caused by the shot-peening operation and their redistribution after fatigue testing in a nickel-based polycrystalline superalloy with a 40 µm average grain size.
