Abstract
This article reports a martensitic transformation from an incommensurate state with a nano-scale domain-like structure in a Ti–42Ni–8Fe alloy. The martensitic transformation is suppressed at a temperature above 4.2 K under zero stress, but occurs under a compressive stress. The product phase is most likely to be the R-phase, but there is a large temperature hysteresis of about 87 K.
