CUBIC-TETRAGONAL TRANSFORMATION AND REVERSIBLE SHAPE MEMORY EFFECT IN MANGANESE-COPPER ALLOYS.

Abstract

The structural change and shape memory behavior in quenched Mn-(5-20) at%Cu alloys have been studied at normal and elevated temperatures. The behavior of shape recovery on heating and cooling is discussed on the basis of metallographic and electron microscopic observations. Residual magnetic ordering is responsible for a reversible shape memory effect.
