In X-ray stress measurement of metals having a texture, the intensity of the diffracted X-rays is dependent on the direction of the stress measured, and is different from that of a randomly oriented metal. The relation between the nature of texture and the intensity of the diffracted beams is analyzed in the present paper and the texture in the cold-rolled steel sheet is determined by using the diffracted intensities in X-ray stress measurement. Then the X-ray elastic constant of the rolled sheet is calculated by considering the anisotropy of crystal and the presence of texture. The X-ray stress evaluated using the X-ray elastic constant thus obtained is in good agreement with the mechanically applied stress, indicating that the present method is applicable to the stress measurement in the case when the texture is not determined.
