The present paper describes the role of Mn on the properties of a Cu-Al-Ni-Zn shape memory alloy. The effect of addition of different amounts of Mn has been studied on a Cu-12Al-4Ni-10Zn alloy, known to exhibit shape memory properties. The transformation temperatures, phase precipitation and thermal properties have been determined. It has been found that the quantity of Mn has a significant effect on the formation, morphology, and structure of the obtained martensite. Therefore, the properties of these alloys are varied in accordance of these effects. The efficacy of adding Mn and its quantity has been described in this study and a correlation is attempted to relate it to the thermal properties.
