Superelastic shape memory alloys (SMA) are able to change the phase when charged with an external mechanical tension. On this occasion a material, that shows e.g. an austenitic phase at room temperature will be changed into stress-induced martensitic phase. On the stress-strain-diagram this change of the lattice structure can be seen in a relatively wide ranged pseudo-plastic deformation at nearly constant force.
