Abstract

Effects of deformation and thermal cycling on damping capacity of Co-21 mass% Mn alloy have been studied. The thermal ε martensite produced during cooling improves the damping capacity of the alloy. However, the ε martensite formed by deformation or thermal cycling treatment deteriorates the damping capacity. The reason is that the dislocations introduced during the deformation or thermal cycling treatment interrupt the movement of damping sources such as stacking fault boundaries in ε martensite.
