Abstract: The effect of heat treatment on the volume effect $\Delta V/V$ and the shape recovery during the martensitic transformation in a Fe-24 at% Pt alloy is studied. An increase in the annealing time from 0 to 300 min at 650$^\circ$C is found to decrease $\Delta V/V$ gradually from 1.26% for the quenched state to 0.987% for $\tau$ = 300 min. The characteristic temperatures of the martensitic transformation decrease and the transformation hysteresis passes through a minimum. The shape memory effect in heat-treated samples reaches 100% after gT = 40 min.
