Experimental data for 55/45 Ni-Ti alloy (Nitinol) is presented in this work for correlation to phenomenological and thermodynamic/micromechanical constitutive and transformation models for shape memory alloys. Hysteresis data is used to obtain the transformation temperatures Ms-martensitic start, Mf-martensitic finish, As-austenitic start, and Af-austenitic finish. Nitinol wires are mechanically tested in tension at five different temperatures: below Mf, at (Ms + Mf)/2, at (M2 + As)/2, at (As + Af)/2, and above Af. For the phenomenological models, several characterization parameters are required. These are obtained experimentally and the models are correlated with the data.
