In this present study, the particulars of an experimental investigation on the effect of nickel addition on microstructural, strain recovery and strain absorption capacity of ternary (Cu–Al–Mn) shape memory alloys has been deliberated. Six dissimilar compositions with varying amounts of Ni in (Cu–Al–Mn) shape memory alloys have been synthesized and investigated to measure their potential for structural applications. Microstructural and detailed phase analysis has been studied. Additions of Ni have enhanced the tensile strength of these alloys. These compositional variations have influenced shape memory and damping properties in from of dissipated strain energy as well as the super elasticity of the alloys.
