Abstract Scope The reactions of K2TiF6 with an Al-Si alloy melt produce Al3Ti reinforcing particulates in-situ in the Al-Si alloy for aluminum matrix composites (MMCs). Si participates in the formation of the reinforcing particulates resulting in the modification of the in-situ particulates and increased mechanical properties. Si exists in the Al3Ti particulates as finely dispersed particles preventing the formation and propagation of cracks in failure. Si toughens the otherwise brittle Al3Ti particulates for a combination of high strength and high ductility. Al3Ti forms a coherent interface with the aluminum matrix resulting in an effective load transfer from the matrix to the reinforcing particulates. The formation of Si particles in the in-situ Al3Ti particulates provides an effective means of producing high strength MMCs with a high ductility.
