Abstract:
The properties of metal matrix composites (MMCs) can be tailored by changing the matrix compositions, the shape and type of reinforcements. Among the design of MMCs, the control of interfacial conditions is the key point. In this paper, the research progress on the control of MMCs interfaces has been reviewed, including the inhibition of harmful interfacial reaction in Cf/Al composite and generation of self lubricating interface in TiB2/Al composite by process control; the control of harmful interfacial reactions in SiC/Al and Cf/Al composites by matrix alloying; the obtaining of W/Cu solid solution interface. It has been proven that the process control and matrix alloying are simple, effective and lowcost methods to avoid harmful interfaces and acquire beneficial interfaces by suppressing the thermodynamics process.
