TiB2 particulate reinforced magnesium matrix composites were successfully fabricated by adding a TiB2–Al master alloy processed via the flux-assisted synthesis (FAS) reaction into molten magnesium. X-ray diffraction (XRD) analysis and microstructural characterization of the TiB2–Al master alloy revealed the formation and uniform distribution of TiB2 reinforcements. By stirring, magnesium matrix composites with dispersed homogenously TiB2 particles can be obtained. Microstructural characterization of the TiB2/Mg composites revealed retention of hexagonal or rectangular TiB2 particulates with the size of about 1 μm.

Woodceramics is a kind of porous materials, which is proved to be an attractive material because of its some favorable characters. Based on its character of interconnected porous structure, woodceramic/metal composites with interpenetrating network are fabricated by the infiltration of molten metal at high temperature. The microstructure and mechanical, damping properties of woodceramic/metal composites were studied. The results indicate that this kind of materials has good potential application value.

This work presents a thermodynamic model to theoretically predict the component activity in multicomponent liquid alloy based on the Wilson equation and an extended Miedema model. Using only the physical parameters of pure metals, the component activities can be theoretically calculated and the calculation results agree well with the measured data. The model should enable very useful predictions to be made for activities in multi-component liquid alloys, especially for the trend of the activity changes with increasing alloy content.
