MICROSTRUCTURE AND REVERSE SHAPE MEMORY EFFECT IN A Cu-Zn-Al ALLOY
Cu—Zn—Al合金逆形状记忆组织的电镜观察

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 up to 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 the parabolic configuration of side interface of bainite plate and the twisting of intersected bainite plates.
