Abstract

The stress of each grain in anisotropic materials having a texture under uniaxial tension was analyzed by using G. I. Taylor's model. The average lattice strain in grains subjected to X-ray diffraction was also calculated by taking account of the stress condition and the volume fraction of grains. The results were examined experimentally by means of X-ray diffraction for hot rolled steel sheets. It was found that the lattice strain of anisotropic materials depended upon the tensile direction of the specimen and differed from that of materials without a texture. Calculated values of lattice strain agreed well with the experimental results, indicating that the stress in each grain depends upon its crystal orientation, and the critical resolved shear stress in each slip system can be regarded as equal in the initial stage of the plastic deformation.
