Abstract:
We have performed comparative analysis of functional properties and functional fatigue of alloys of the Ni–Mn–Ga system in the initial molded state and the Ni–Ti system in the initial hot-forged state without thermal treatment. It is shown that the Ni$_2$MnGa alloy in the molded state is preferable for low-loaded actuating elements (up to 100 MPa) and low recoverable strains (up to 1.5%) in the temperature range from –85 to –75$^\circ$C; the Ni–Ti system alloy in the hot-forged state should be used for high-loaded actuating elements (up to 500 MPa) and high recoverable strains (up to 8.5%) in the temperature range from –40 to 40$^\circ$C.
