Abstract
A series of uniaxial experiments of nearly equiatomic NiTi alloy wire performed in the temperature range of approximately -20 to 100 °C were conducted in liquid media as well as in temperature controlled air. The as-received material was in the R-phase at room temperature and transformed to martensite and austenite by changing its temperature or by the application of stress. The transformation stress and the overall mechanical response of the material are very sensitive to the temperature, loading rate, strain range, thermomechanical history and specimen geometry. A brief sketch of the model being used to simulate the thermoelastic response of the shape memory alloy NiTi is presented.
