Abstract: The athermal/isothermal nature of the B2↔B19’ martensitic transformation was investigated by means of electrical resistance measurements in a Ni49.5Ti50.5 alloy that has elevated transformation temperatures as compared with the near-equiatomic or Ni-rich compositions studied previously. The direct B2–B19’ martensitic transformation shows a clear time dependence, whereas isothermal effects are not revealed for the reverse B19’–B2 transition. The applicability of the C-shaped time–temperature–transformation diagram to interpret the experimental results is discussed.
