The composite materials fabricated by MIM so far include the matrixes of steel, refractory metal, intermetallic com￾pounds, and titanium alloys with various types and forms of reinforcements. Bimetal composite structures can be pro￾duced by MIM through co-injection of different types of feedstock or molding a powder over a solid core as well. Furthermore the microMIM has shown the capacity of manu￾facturing composites at micron scale. Limitations and needs of the technique in composite fabrication are also presented in the literature. Previous research has demonstrated the feasibility of fabricating advanced composites and compo￾nents using the MIM approach. The full potential of MIM process for fabricating metal matrix composites is yet to be explored. references Alcock, J., 1999. Co-injection promises further growth for MIM. Metall.
