Abstract: The metal matrix ceramic composite,Li5La3Ta2O12/Al, was prepared by powder metallurgy method. It was found that the damping capacity and the mechanical properties of the composite at room temperature are greatly enhanced in comparison with the pure Al. The damping capacity of the 20%Li5La3Ta2O12/Al composite can reach 0.010, which is one order of magnitude higher than that of pure Al, and the corresponding yield strength and microhardness of the composite are 43% and 28% higher than those of pure Al, respectively.
