Nickel-titanium shape memory alloys - Material data sheets

A_f: temperature at which martensitic transformation ends during heating.

A_p: temperature at which the transformation to austenite on heating is around 50% and corresponds to the peak on the curve measured by differential scanning calorimetry (DSC).

A_s: temperature at which austenitic transformation begins during heating.

Austenite: stable phase at high temperature.

DSC: differential scanning calorimeter, a method used to measure transformation temperatures in NiTi alloys by detecting the variation in heat flow due to transformation during heating.

Hysteresis: temperature difference between the transformation on heating and the reverse transformation on cooling. For NiTi alloys, hysteresis is generally provided by the difference between the A_p and M_p temperatures.

M_f: temperature at which martensitic...
