Abstract: SiCp/Al composites fabricated by compocasting method was heated to different temperatures and held for a certain period in order to change interfacial reaction degree. The interfacial reaction kinetics was studies by determining silicon concentration in the composites and its relation with two effecting factors, temperature and time. A dynamic equation was derived and several parameters which have definite physical implication were calculated from the equation, such as the starting temperature of the interfacial reaetion, velocity constant of the interfacial reaction and so on.

Key words: SiCp/Al composites, iuterfacial reaction, velocity constant
