Stress-strain curves of Ni₅₄Fe₁₉Ga₂₇ single crystal at the low strain rate of 0.002 s⁻¹ without the stress-holding process (a) and the corresponding time dependence of temperature and stress variations (c) and at the high strain rate of 0.017 s⁻¹ with the stress-holding step (b) and the corresponding time dependence of temperature and stress variations (d).
