Abstract:
Researchers aronnd the world conducted experiments according to the aspects of interfacial reaction principle, contributing factors, control approaches, etc. In the aspect of interfacial reaction principle, possibly existing interfacial chemical reaction between Al alloy liquid and SiC particles, interfacial reaction process and model, phases in the interface, etc. , have been researched. In the aspect of contributing factors to interfacial reaction, the relationship among interfacial reaction and process, parameters of fabrication such as effect of Mg, Si content, SiC pretreatment, temperature, cooling speed to interfacial reaction has been investigated. In the aspect of efficient control approaches to interfacial reaction, matrix alloying, surface treatment to SiC particles, process selection and process parameters control have been studied. Research direction of interfacial reaction for the future can be generalized as the following aspects; interfacial fine structure, chemical thermodynamics and kinetics of interfacial reaction, establishment and optimization of heat and mass transfer model to interfacial reaction and new efficient control approaches to interfacial reaction.
