Özet
This study reports the investigation of transformation temperatures of aged Cu- Al-Mn shape memory alloys with low-rated Mn (< 5 wt.% Mn). A total of 21 different Cu-Al-Mn based chemical compositions were fabricated using the arc melting method and aged at 450°C for 120 min after quenching at 900°C. An electron to atom (e/a) ratio of 1.391 to 1.576 was obtained from all samples. The transition temperatures of martensite and austenite were defined using a Differential Scanning Calorimetry (DSC) device and the unit cells structures were analysed performing the X-ray diffraction (XRD) technique. Furthermore, the sensitivity of Al and Mn elements to transformation temperatures was determined.
