Studies on Line Structures in Single Crystals of Tin (1st Report)

Hideo Takaki, Masashige Koyama and Hidekiyo Fujihira


Abstract:

Line structures termed ``corrugations'' and ``striations'' by Chalmers et al., were studied microscopically with single crystals of tin of the purity of 99.87% grown from the melt, in which the [110] direction was parallel to that of the temperature gradient. The same line sturcture as corrugations was observed on the side surface of the specimens, and the so-called cell structure was also observed on both the free top surface and the etched sectional one. However, it is noticeable that the line structure observed on the (110) plane was irregular despite its regularity on the (001) plane, and further that a tortoise-shell pattern was observed on the (110) plane, probably owing to the low purity of specimens. It was also found that the striation boundaries coincided always with the corrugation boundaries on the side surface of the specimens.
