“…Recently, considerable efforts have been made to seek ternary additions for extra functionality such as control of transformation temperatures and hysteresis [7][8][9]. The addition of ternary elements can produce lower transformation strain levels and lower slip strength in many cases compared to binary NiTi [10].…”

We report on unprecedented transformation strains exceeding 20% in tension for Ni 50.5 Ti 36.2 Hf 13.3 shape memory alloy (SMA). The strain measurements were made at multiscales utilizing advanced digital image correlation. The display of excellent strain reversibility in shape memory (isothermal deformation between M f and A f ), isobaric thermal cycling (between M f and A f ), and superelasticity experiments (deformation above A f ) confirm a wide range of functionality. The ultrahigh strains in [111] orientation exceed the lattice deformation theory predictions possibly pointing to contributions from mechanical twinning effects. The high strength levels and large strains result in very high work outputs compared to other SMAs.
