摘要：

TiC reinforced magnesium matrix composites were successfully synthesized by spontaneously infiltrating molten magnesium alloy into AI-Ti-C preforms and in situ forming TiC particles in the liquid of magnesium alloy. Damping capacities of in situ TiC reinforced magnesium matrix composites were investigated. Experimental results show the damping capacity of the magnesium alloy increased with the increase of reinforcement percentage. Improved damping capacities of composites can be attributed to dislocation damping mechanism at room temperature. At elevated temperatures, interface damping becomes a new contributor to the increase of damping capacity. (C) 2008 Elsevier B.V. All rights reserved.
