A plate specimen of austenitic stainless steel was prepared, and a plastic strain of 2.8% was applied to the specimen under uniaxial tension. The residual stresses of the specimen were measured by the cos2x method using multiple lattice planes. For lattice planes with a lower atomic density, the 2θ-cos2x diagram showed an upward warp. For lattice planes with a higher atomic density, the 2θ-cos2x diagram showed a downward warp. This phenomenon is caused by intergranular strains. The strain distribution for each lattice plane was measured in the direction from 0° to 180° with a step of 5°. As a result, the strain of the lattice plane for low atomic density balanced that for high atomic density. The intergranular strain depends on the lattice plane and the azimuth. The intergranular strain due to plastic deformation affects the X-ray stress measurement.
