【Abstract】 In this paper, the effects of microalloying elements and other alloying elements on damping capacity and mechanical properties of cast iron is described. The results of experiment showed that, when the additive level ofZr、Cr、Mo、Cu and Al are proper and well coordinated one another for microalloying elements and other alloying elements, the specific damping index of cast iron may be increased by 20 per cent or more-and the tensile strength of up to 172~202 MPa was achieved.更多还原
