摘要：

The effects of aging on transformation temperatures, morphology and atom arrangement in Cu-Zn-Al shape memory alloys have been examined by differential scanning calorimetry (DSC), transmission electron microscopy (TEM) and channelling enhanced microanalysis (ALCHEMI), respectively, and they have been investigated for both the parent and the martensite phases by using Cu-11.4Zn-18.7Al and Cu-11.2Zn-17.1Al (at%), respectively. The aging in the parent phase did not change significantly the transformation temperatures and the atom arrangements. On the other hand, the aging in the martensite phase increased reverse transformation temperatures. This increase was attributed to some change in atom arrangement and to some decrease in the density of stacking faults during aging.
