STUDY OF ATOMIC MOTIONS ON TWINNING OF AN ORDERED ALLOY.

Abstract

A model for the twinned structure of Mg3Cd from its ordered, hexagonal state is derived from the classical twin indices for (1012) twinning. Use of these indices transforms the ordered hexagonal Mg3Cd into an ordered orthorhombic structure having identical atom positions as the hexagonal structure, but with a different sequence of magnesium and cadmium occupancy. This different sequency gives rise to additional x-ray super lattice lines which were analyzed theoretically and experimentally with respect to the postulated model. (Author)
