Six microcrystalline alloys rapidly quenched from the melt (Ni64Al36, Ni65Al35, Ni66Al34, Ni56Al34Co10, Ni64Al32Si2, and Ni64Al32Cr4, at %) have been investigated using polythermal and isothermal resistometry with a subsequent microstructural analysis. The absence of reversibility of the thermoelastic martensitic transformation for all these alloys (except for Ni64Al36 and partly Ni56Al34Co10), the reason for which is a strong tendency to a diffusive decomposition of the fresh (as-quenched) martensite of these alloys has been revealed. New regimes of stabilizing annealing that enable application of high-nickel alloys based on nickel-aluminum martensite as functional materials with a high-temperature shape-memory effect have been suggested.
