Conclusion
Martensite transformation in alloys of the system Cu−Al−Nb occurs at temperatures much above 200°C. The hysteresis of the reversible martensite transformation is 108–128°C, which is less than for alloys of the system Cu−Al−Ag [3]. Alloys of the system Cu−Al−Nb possess a high effect of shape memory and an elevated ductility and strength. The degree of recovery of shape for an alloy with 2.56% Nb exceeds 90% at σГ MPa and δ20=12.7%
