Abstract The bainite structure related to the reverse shape memory effect has been observ-ed by means of TEM in a Cu-Zn-Al alloy. The reverse memory effect may be improved upto one order of magnitude under applied constraint stress. The widespread propagation of bai-nite was confirmed to be the diffusion controlled shear process by phenomina observed both theparabolic configuration of side interface of bainite plate and the twisting of intersected bainiteplates.
