Abstract: The interfacial reaction behavior during the remelting of SiC_p/Al composite with different volume reinforcement has been studied by liquid metal X-ray diffraction (LMXRD) and differential scanning calorimeter(DSC). Experiment results show that the interface reaction during remelting is associated closely with the reaction during fabrication; chemical reaction is strengthened during fabrication due to high reinforcement volume fraction,but it is not susceptible to the reinforcement fraction and the remelting number during multiple remelting. The mechanism of reaction dynamics which controls the evolution of chemical reaction during remelting is also presented.
