A mathematical relationship is set up between the recovery ratio andordering degree, probability of atoms at their ordered sites, grain size, the widthof the grain boundary affected regions, the stress during deformation, as well as thecritical shear stress. Shape memory effect reaches a maximum with varying grainsize and increases linearly with increasing ordering parameter, that agrees well withexperimental results. Key words:  CuZnAl alloy      ordering degree      grain size      Received:  18 March 1989      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1989/V25/I3/17 1 Perkins J.
