A simple cast joining process between reaction-bonded SiC and aluminum has been investigated. Processing variables to obtain strong bonding strength were examined. Metallurgical observation showed that an SiC particle/Al-Si alloy composite layer was formed between RB-SiC and solidified aluminum, and Al4C3 was formed between the SiC particle, in the composite layer, and the Al-Si alloy matrix. Formation of Al4C3 and the composite layer was controlled by casting temperature and time, respectively. The bonding strength increased with decreasing of an unjoined area which formed at the joined surface.
