Effect of heat treatment on the white layer and its effect on the damping behavior of metal matrix composites

In the present study, the effect of heat treatment on the white layer and its effect on the damping behavior of the rice husk ash (RHA) reinforced metal matrix composites have been studied. The damping measurements were performed using dynamic mechanical analyzer. The specimens for damping measurements were machined using wire cut electric discharge machining (EDM) process. The results show that the white layer has a great influence on the damping capacity of the composites.
