The present paper focuses on the relation between damping capacities and the addition amount of Si. The results show that damping capacities increase with increasing amount of Si. Particular emphasis is placed on the increasing dislocation density around matrix-particulate interface and the refinement of grain size promoted by big growth restriction factor of Si.

The damping capacity of foundry composites and heat-treated composites is described. In order to investigate the relation between damping capacity and strain amplitude, temperature, a series of experiments is given. The research results confirmed that heat treatment is advantageous to improving damping capacity of the composites. In addition, heat treatment can change the location of temperature-damping peak on temperature-damping curve. The effect of heat treatment on damping capacity and the damping mechanism is explained through dislocation motion and grain boundary slip.

And measurements were performed on the composites. The results of x ray diffraction (XRD) analysis confirmed that TiC particulates were synthesized during the sintering process, and they retained in magnesium matrix composites after the remelting and dilution processing. From the microstructure characterization and electron probe microanalysis (EPMA), we could see that fine TiC particulates distributed uniformly in the matrix material.
