摘要

Effect of carbon and Ti on r<->e martensitic transformation behavior and damping capacity has been investigated in an Fe-17Mn alloy. The suppressive force of carbon against y-*e transformation increases linearly with an increase in carbon content, lowering Ms temperature and volume fraction of E martensite. Carbon deteriorates damping capacity by reducing the area of y/c interfaces and by decreasing the mobility of the interfaces operated as damping source. The reduction in the mobility of the interfaces is accelerated when carbon-containing alloy is aged at high temperatures. The effect of Ti on the damping capacity is found to be beneficial in carbon-containing alloy, because the Ti contributes to depletion of carbon solute by the formation of TiC.
