%X A new kind of metal matrix composites with the matrix of pure magnesium and the reinforcements of hybrid SiC. and Al2SiO5f was fabricated and the relationships of its damping capacity with strain amplitude, frequency and temperature were studied in this paper. It is found that the damping capacity of the composite is lower than that of pure magnesium at room temperature, but when temperature is elevated it is increased and beyonds the damping of pure magnesium. It is concluded that damping mechanism of the composite at room temperature is the movement of dislocations In the Mg matrix part and at high temperature it is mal contributed to the inteffoce damping.
