ORDERING AND DEFORMATION PROCESSES IN MAGNESIUM: CADIUM ALLOYS,

Abstract

The kinetics and mechanism of ordering in alloys with composition near Mg3Cd were studied using electrical resistivity. X-ray diffraction and transmission electron microscopy. In specimens quenched from above T sub c the ordering process was found to be heterogeneous, occurring by the nucleation and growth of ordered domains. The antiphase domain boundaries in ordered specimens do not lie in preferred crystallographic planes but otherwise show similarity to the Cu3Au system. The mechanical properties and deformation characteristics of ordered and disordered specimens were investigated over a range of temperatures. The mechanical properties of ordered and disordered specimens differ considerably at room temperature. Preliminary analysis showed that different slip planes are operative in ordered and disordered specimens. (Author)
