| Abstract: | Bulk Mg65Cu20Ag5Gd10 metallic glass matrix composites reinforced by SiC particulates were synthesized and characterized. Thermal stability and glass forming ability of the matrix are not significantly affected by the particle addition. Compressive fracture strength of the SiC particulates reinforced composite reached about 963 MPa, a factor of 1.2 higher than monolithic glass. A small quantity of Si atoms diffusion can be detected in the composite, but no reaction layer can be observed. |
