Kinetic Analysis of Cu-8.3 wt.%Al-9.4 wt.% Mn Shape Memory Alloy

In this paper, the transformation temperatures of Cu-8.3 wt% Al-9.4 wt% Mn shape memory alloy were investigated. Martensitic and austenitic start and finishes temperatures were determined by differential scanning calorimeter at five different heating/cooling rates: 5, 10, 15, 20 and 25 °C/min. The DSC scans were performed in 3 heating/cooling cycles. DSC results showed mostly two exothermic peaks at cooling scans, with Ms = 68 °C for rate of 25 °C/min till Ms = 41 for rate of 5 °C/min . Ms temperatures and hysteresis decrease with decreasing heating/cooling rate.
