A novel phase transition in alloys
Conference

OSTI ID:5160003
The intermediate-phase of the intermetallic alloy CsPb is shown to be a plastic crystal characterized by jump reorientations of Cs{sub 4}Pb{sub 4} structural units. The wave vector variation of elastic and quasielastic intensities is well reproduced by a simple model if independent structural units jumping between the four orientations observed in the crystal at room temperature. This represents the first observation of a plastic crystal phase in a metal alloy. 17 refs., 6 figs.
