X線回折顕微法によるアルミニウム結晶のすべり帯の解析

抄録

X-ray diffraction micrographs of slip bands have been taken by the Berg-Barrett method, using elongated aluminium single crystals. It has been found that the lamellae S running parallel to the slip bands shift laterally with the change of the glancing angle, the direction being opposite for the neighbouring lamellae. This shift can be interpreted as the existence of twists on the slip plane whose directions are opposite for the neighbouring slip bands. In addition it has been found that the lamellae S have locality characters: The spotty reflection and the discontinuous lateral shift. These characters show the existence of the local lattice curvature at the slip bands.
