The suppressive force of carbon against gamma <-> epsilon transformation increase linearly with an increase in its content, lowering Ms temperature and volume fraction of epsilon martensite. Carbon deteriorates damping capacity by reducing the area of gamma/epsilon boundaries and mobility of the boundaries contributing to anelastic deformation. The reduction in the mobility of the boundaries is accelerated when carbon containing alloy is aged at higher temperatures than room temperature. The effect of Ti on damping capacity is found to be beneficial in carbon-containing alloy, which is attributed to the depletion of carbon solute due to the formation of TiC.
