The damping capacity of Co-Mn system which undergoes fcc → hcp martensitic transformation has been studied as a function of ε volume fraction using an inverted torsional pendulum. The damping capacity increases linearly with increasing ε volume fraction regardless of manganese content, and is represented by δ = 0.05 + 0.27 fε where δ is the damping capacity in logarithmic decrement of Co-Mn system and fε is the ε volume fraction. The main damping mechanism of Co-Mn system containing ε martensite is the movement of stacking fault boundaries in ε martensite plates.
