This study was carried out to investigate the effect of reverse transformation on the damping capacity in high manganese austenitic stainless steel. ${alpha}^{prime}$-martensite was formed with the specific direction and surface relief by deformation. Over 95% of the austenite phase was transformed to deformation-induced ${alpha}^{prime}$-martensite by 70% cold rolling. Reverse transformation became rapid above an annealing temperature of $550^{circ}C$, but there was no significant transformation above $700^{circ}C$. In addition, with increasing annealing time at $700^{circ}C$, reverse transformation was induced rapidly, but the transformation was almost completed at 10 min. Damping capacity was increased up to $700^{circ}C$, and than unchanged with the increasing annealing temperature. Damping capacity increased steeply with an increasing reverse treatment time up to 10min, whereas there were no significant change with a treatment time of more than 10 min. Damping capacity increased with an increasing the reversed austenite and was strongly affected by reversed austenite.
