Abstract

The residual stress in a subsurface layer of austenitic stainless steel with a finished surface was evaluated by the polychromatic X-ray method. A surface of austenitic stainless steel SUS316 plate was ground and lapped as the specimen. In this method, the relation between strain and depth was approximated with a linear function or an exponential function, and it was assumed that the plane stress state existed in each subsurface layer in the depth direction of the specimen. As a result, the residual strain which was estimated under the assumption of the exponential function showed more reasonable distribution than that of the linear function. In addition, the residual stress which was calculated from the strain distribution was maximum tension at the surface of the specimen, and maximum compression at a position 3 μm below the surface. Therefore, the steep gradient of residual stress could be confirmed in a subsurface layer of the SUS316 with a finished surface.
