Abstract: An investigation of the influence of deformation on shape recovery has been put forward in Cu-Zn-Al shape memory alloys.Starting at a model of the re-orientation of martensitic va- riants,the principle and essentiality of the influence of the amount of pre-deformation ε on shape recovery rate η is elucidated.

Key words: shape memory alloy, martensitic variant, re-orientation, CuZnAl alloy
