| Abstract: | The shape memory capacity and the shape memory life of three alloys of the Cu11 6Al0.4BeX type have been investigated by the strain angle restoration method and compared with the alloy Cu24 5Zn4Al. The alloys were subjected to various normalizing treatments and normalizing plus aging treatments, and all of them were found to possess excellent shape memory properties. The alloy Cu11.6Al0.4Be0.2Cr demonstrated the best shape memory capacity and life. |
