The directional dependence of mechanical behavior of pre-deformed polycrystalline metals is very important for the plasticity and the plastic working. X-ray diffraction techniques are believed very useful to study these anisotropic deformation properties, since some microscopic parameters concerned with such phenomena can be detected by these methods. In the present paper, the microscopic parameters obtained from the integral breadth of X-ray diffraction profile and from the shape of X-ray micro-beam pattern are examined on an Al-stabilized steel sheet pre-stretched to the strain of 12 percent in the direction of temper rolling. The results obtained are summarized as follows : (1) The directional dependence of integral breadth of diffraction profile, and also of the particle size and the effective strain calculated from the integral breadth, are observed on the material used. (2) The diffraction spots obtained by the X-ray micro-beam method give different values of subgrain size and total misorientation when the directions of their diffraction are different from each other with respect to the direction of the tensile axis. (3) The directional dependence of these microscopic parameters has some relation to the orientation of tensile axis of each crystal contributing to the diffraction.
