Summary

In this study, the production of CuZnAl shape memory alloys by powder metallurgy from elemental powders was investigated. It has been found that conventional powder metallurgical route via cold compaction and sintering is not applicable to the mixtures of elemental Cu, Zn and Al powders due to the vaporization loss of zinc. However, hot pressing, which is a novel technique in such mixtures, has been determined to be an effective method preventing zinc loss. Furthermore, by hot rolling followed by this novel technique, homogeneous CuZnAl alloys that exhibit shape memory behaviour could be produced from elemental powders.
