Abstract : The ability of polycrystalline Cu-Zn-Al alloys to demonstrate increasing percentage two-way shape memory (TWSM) displacements with 'training' is investigated. Results indicate a definite relationship between increased cycling and increased TWSM ability. The empirical training cycle curve parameters are presented and shown to change with cycling. Most parameters show a decreasing trend. Transmission electron microscopy of trained alloys is conducted in an effort to mechanistically explain TWSM training. (Author)
