The sub-structure of crystals of silicon-iron alloy

Abstract

After electrolytic polishing and etching a network of boundaries between mosaic blocks was observed on the surface of single crystals of silicon-iron alloy prepared from the melt. Some of the boundaries are formed by a number of distinguishable pits, also found singly outside the boundary. An explanation is given on the basis of the conception that the pits are etched points of intersection of edge dislocations with the surface of the crystals.
