| Abstract: | The Li5La3Nb2O12/Al composite was prepared by powder metallurgy method. The damping capacity of the composite as high as 0.011 was obtained at around 325K for the measuring frequency of 1.6Hz, which is five times higher than that of the pure Aluminum at the same temperature province. More importantly in purpose of practical application, the damping capacity of Li5La3Nb2O12/Al--80% composite at the temperature range from room temperature to around 400K. |
