The shape memory capability and life of CuAlBeX alloys

Abstract The shape memory capacity and the shape memory life of three alloys of the Cu11.6Al0.4BeX type have been investigated using the strain angle restoration method and compared with the alloy Cu25Zn4Al. The alloys were subjected to various normalizing and normalizing plus aging treatments, and all were found to possess excellent shape memory properties. The alloy Cu-11.6Al-0.4Be-0.2Cr demonstrated the best shape memory capacity and life.
