Crystallographic orientation of a recrystallized grain grown in a strained single crystal of ice

Abstract

A rectangular solid sample, made from a single crystal of ice, with a grid of grooves cut on its top face, was uniaxially compressed and then annealed to allow recrystallization. Crystallographic orientations were determined by the transmission Laue method, and additional studies were made of the orientation distribution of the recrystallized grains and the growth process. Many fine grains recrystallized at the grooved face at the beginning of annealing but only a few grew into large grains invading the lower portion of the crystal on continued annealing. Although the fine grains were randomly oriented, the large grains appeared to show some preferred orientation to the 〈0001〉 axis of the matrix. The results are interpreted using a kinetic theory of recrystallization.
