Abstract |
Shape memory effect is a peculiar property exhibited by certain alloy system, and shape memory behavior
is evaluated by the structural changes in microscopic scale. Shape-memory effect is based on martensitic
transformation, which occurs on cooling from high-temperature parent phase region with the cooperative
movements of atoms on {110}-type close-packet planes of parent austenite phase by means of
shear-like mechanism. The material changes its internal crystalline structure with martensitic transition,
and the ordered structure or super lattice structure is essential for the shape memory quality of the material.
Copper based alloys exhibit this property in metastable B-phase field which has bcc-based high symmetric
structure at high temperature parent state. These structures turn into non-conventional stacking
ordered structure with low symmetry following two ordered reactions on cooling from high temperatures.
