TiC/Al composites with high TiC particle content is prepared by SHS(Self-propagating High-temperature Synthesis)process.The uniform distribution process of TiC particles in the stationary zinc melt is studied and analyzed by using self-made experimental equipment.The results show that zinc diffuses into the TiC/Al composites after they are placed in the zinc melt at temperatures below the melting point of aluminum,which leads to the decrease of the liquidus temperature of Al-Zn alloy in the surface layer of...
