A structural-morphological study of a Cu63Al26Mn11 shape memory alloy
By means of DSC, three transformations occurring on heating up to 873 K, of a martensitic Cu63Al26Mn11 Shape Memory Alloy (SMA) in hot pressed and homogenized state, were revealed. The assumed precipitation of α-phase, accompanied by an exothermic reaction, was ascertained by SEM mapping. SEM micrographs revealed preferred orientation tendencies for the α-phase precipitates, inside the grains which became more prominent along grain boundaries
