N2 - The effect of the melt cooling rate on the atomic ordering of austenite and, as a consequence, on themartensitic transformation of a nonstoichiometric alloy of the Ni-Mn-In system has been studied. In-situ TEMobservations revealed differences in the mechanism of phase transformations of the alloy subjected to differentcooling conditions. It is shown that during quenching a high density of antiphase boundaries (APB) is formedand the alloy is in the austenite-martensitic (10M and 14M) state up to a temperature of 120K. In a slowly cooledalloy, a lower APB density is observed, and a two-stage transformation L21/B2 → 10M → 14M occurs in therange of 150–120 K.
