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...
