erks ised ine Using in situ digital image correlation to obtain full-field measurements, we study the intermartensitic transformations in single-crys-tal NiFeGa. Full-field strain measurements identify the coexistence of modulated martensite phases during the first plateau of the mul-icant scientific and technological interest. The reversibility In previous studies, researchers inferred the formation of different martensitic phases by means of indirect evi-dences, such as comparison of the plateau strain with the-material volume completely transforms. Potential draw-Recent investigations have identified that intermarten-sitic transformations result in a multistage stress–strain curve with two plateaus in NiFeGa when loaded in tension at room temperature [3–6]. Sutou et al. [3] reported that the intermartensitic transformation sequence at room tempera-ture is A? 14M? L10 for a [105] oriented NiFeG
