The shape memory steels have recently received much attention, from which a considerable progress has been achieved in understanding the factors which are of particular importance for their development. Among these steels, a special interest has been paid to the ferromagnetic Fe-Ni- and Fe-Co-based alloys mainly because of the thermoelastic character of the fcc ({gamma})-bct ({alpha}) martensitic transformation that they exhibit under the action of temperature (shape memory effect), stress (superelasticity) and magnetic field (magnetoelasticity). In the present work the authors report the results of the experimental investigation about the {gamma}-{alpha} thermoelastic martensitic transformation in Fe-Co-Ni-Ti alloy using different techniques (notably DSC, DMA, dilatometry, TEM and magnetic susceptibility). One of the objectives was to find the appropriate thermal treatments in order to increase the martensitic transformation temperatures up to room temperature.
