In order to learn about the lattice recovery processes responsible for that, variations of tensile force, electrical resistance and synchrotron X-ray diffraction signal from 0.1 mm thin as-drawn Ni-Ti wire prestrained in tension were recorded simultaneously during the short time electric pulse treatment. The data were used to obtain direct experimental information on the phase fractions, internal stresses and defects in the microstructure fast evolving in response to the prescribed temperature and tensile stress in the treated wire.
