Reactive stresses in Ni$_{49}$Fe$_{18}$Ga$_{27}$Co$_{6}$ shape-memory-alloy single crystals

The reactive stresses induced in Ni$_{49}$Fe$_{18}$Ga$_{27}$Co$_{6}$-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 Ni$_{49}$Fe$_{18}$Ga$_{27}$Co$_{6}$ single crystals in designing drives and power motors is demonstrated.
