The tensile fatigue response of single crystal NiFeGa with [0 0 1], [0 1 1] and [1 2 3] orientations was investigated under pseudoelastic conditions. The [0 0 1] orientation displayed a remarkably long fatigue life, exceeding 13,000 cycles, when loaded to a 10% strain range. The [1 2 3] orientation displayed the shortest fatigue life and the [0 1 1] intermediate. Although the fatigue lives drastically varied for all three orientations, the stabilization of the stress-strain curves was similar. The lack of residual strains and the stability of the stress-strain curves indicate excellent fatigue resistance.
