Re-constructing the phase relations in Co38Ni33Al29 ferromagnetic shape memory alloy
Original language description
Alloys in the Co-Ni-Al system and even their shape memory properties have been studied for decades as the cobalt-based alloys were supposed to have higher transformation stresses and wider intervals of superelasticity than other shape memory alloys (SMA). As these alloys are ferromagnetic the magnetic shape memory effect could be expected like in Ni-Mn-Ga and similar alloys. Additionally, the two-phase structure in the high-temperature austenitic state is an exception within the SMA. It contains a B2 ordered (Co,Ni)Al matrix and A1 fcc solid solution particles. The A1 (interdendritic) particles remain untransformed, whereas the B2 matrix transforms martensitically into the L10 martensite. Only non-modulated L10 martensite was observed in Co-Ni-Al basedalloys.
