摘要：
A sequence of thermally and stress-induced intermartensitic transformations has been found in a Ni52.0Mn24.4Ga23.6 single crystal, which have been confirmed by transmission electron microscopy through in situ cooling experiments. The stress-strain-temperature behavior under compression along the < 110 >(P) and < 100 >(P) crystallographic directions has also been studied for this compound and a stress-temperature phase diagram has been established.
