Direct Observation of Polygonization in Rocksalt

Abstract

POLYGONIZATION has been studied hitherto by means of two different methods: Guinier and co-workers1 used refined X-ray methods, which, however, only permit the detection of orientation differences without localizing the domain responsible for a particular spot; Cahn and others2, on the other hand, used etching techniques to make visible the polygon boundaries. The mean difference of orientation was estimated from the radius of curvature of the bent specimen and the width of the domains.
