摘要：
To improve the fatigue resistance of stainless steel sheet, it is a common practice to induce compressive residual stress in the surface through shot-peening or tumbling. Stress depth profiles obtained by tumbling of thin stainless steel tensile rods were analysed using laboratory and synchrotron X-Ray Diffraction (XRD). Both the non-destructive synchrotron and the laboratory XRD etch-depth profile gave similar results: a residual stress profile decaying over a depth not exceeding 50 mu m into the material.
