Abstract

The reactive stresses induced in Ni₄₉Fe₁₈Ga₂₇Co₆-alloy single crystals during martensitic transformations with a limited possibility of shape-memory-strain recovery have been experimentally studied. The data on these crystals are compared with the results obtained previously for Cu–Al–Ni, Ni–Ti, and Ni‒Fe–Ga crystals. The potential of application of the Ni₄₉Fe₁₈Ga₂₇Co₆ single crystals in designing drives and power motors is demonstrated.
