The relation between the deformation and the integrated intensity of X-ray was investigated with aluminium single crystals, and it was found that with increasing slip deformation the reflected intensity first increased rapidly, and then gradually reached a saturation at about 2 per cent elongation, irrespective of the tensile direction relative to the crystal orientation. The preferential deformation at the surface layer was deduced from the change in integrated intensity of X-ray reflected from specimen of various thicknesses prestrained by a few per cent. It was seen that the region giving a maximum reflected intensity was not the outermost surface of crystal but the inner layer about 10μ from the surface, and that with increasing deformation this region extended into the crystal. Further, the orientation dependence of the reflecting power in a plastically bent state was examined on (111) reflection by a Geiger counter diffractometer, and it was seen that the change in the reflected intensity related to the crystallographical relation of stress direction.
