Evaluation of Shape memory effect and Pseudo elastic effect of Cu-Al-Be-Mn Quaternary shape memory alloys

Abstract Shape memory alloys (SMAs) are the category of advanced metallic materials that in the martensitic phase state can sustain strains above its elastic limit but when heated return to their original shape .shape memory alloys in the austenitic phase state exhibits super elasticity and the material recovers its original shape by removal of force. The shape memory effect and transformation temperatures of the rolled specimens were found out by bending test and by DSC. The alloys were investigated for microstructure by optical micrographs to know the martesite variants .The mechanical properties like tensile strength hardness of the sample were evaluated by using UTM and hardness tester respectively as per ASTM standards.
