We directly observed for the first time that the phase was formed at the initial stage of the plastic deformation and the volume fraction of the phase increased with increasing plastic deformation. This stress-induced martensite phase acts as a nucleation site for the {332}113 twins. Further increase in stress results in a replacement of the phase by the {332}113 twins.
