Abstract
The martensitic phase transformation in a Ni53.6Mn27.1Ga19.3 shape memory alloy is an athermal phase transformation that starts practically, immediately after reaching a certain transient temperature. The final temperature is given at each point of the sample by two processes: heat conduction and phase transformation. Both processes take place in tandem. The thermal expansion and calculation of the temperature fields in a dilatometer are used to determine the transient temperatures and to study the transient temperature ranges.
