Particularities of phase transitions in thermomechanically processed Cu-Al-Mn shape memory alloys

Abstract: Abstract. The thermally and stress induced phase transitions occurring in a Cu-Al-Mn Shape Memory Alloy (SMA) have been investigated by means of thermal analysis techniques, tensile testing and microscopic observations. On heating a hot rolled solution annealed Cu-Al-Mn SMA, up to 873 K, two phase transformations, related to equilibrium phase precipitation and to 2-step order-disorder transition, respectively, were revealed by Differential Scanning Calorimetry (DSC). During tensile testing, the Cu-Al-Mn SMA un… Show more
