Abstract

Austenitic stainless steel was plastically deformed under uniaxial tension, and its plastic strain measured was 2.8%. The micro-residual stress were measured by the cos² _X method using hard synchrotron X-ray with about 70 keV. The 2θ-cos² _X diagrams for the 4 0 0 and 6 2 0 lattice planes, which belonged to a soft lattice plane, showed an upward warp. In contrast, the 2θ-cos² _X diagrams for the 4 4 0 and 3 3 1 lattice planes, which belonged to a hard lattice plane, showed a downward warp. This is caused by the micro-residual strains such as intergranular strains. To investigate detail of the micro-residual stress by plastic deformation, the distributions of the residual strains were measured in omni-azimuth angles. As a result, the micro-residual strains for a soft lattice plane balanced with that for a hard lattice plane.
