A single-crystalline specimen with the composition of Ni49.5Mn38.4Sn12.2 shows a
4.9% recoverable transformation strain upon compressive loading. The critical
compressive stress increases with temperature at the step of 5.6 MPa/K,
whereas upon cycling it decreases by 18.1 MPa/cycle. The microstructure of the
specimen undergoes considerable refinement upon superplastic training; however, it is only able to sustain a limited number of cycles (B 5). Martensite
training, resulting in a single-variant microstructure, has a profound influence
on the austenite start transformation temperature (DT = 29 K), resulting partially from the dissipation of the elastic strain energy. The Ni-Mn-Sn system is
an interesting candidate for multiferroic applications given its mechano-magnetic properties and a huge value of the martensitic transformation entropy
change (* 50 J/kg K).
