As stated in the booklet entitled ``Formation of RM)'',
Compocasting has been known as one of the methods for producing composite materials when the reinforcing material is short fibers or fibers. According to this compocasting method, it is possible to easily produce a composite material with a small volume fraction of reinforcing material compared to other methods.

、従ってマトリックス金属の組成が限定されるという問
題がある。Problems to be Solved by the Invention However, in this composite casting method, the reinforcing material and the molten matrix metal must have good wettability with respect to each other. Therefore, for example, when the matrix metal is an aluminum alloy, Conventionally, Mg and Ca have been added to improve the wetting of the reinforcing material, and therefore there is a problem in that the composition of the matrix metal is limited.

ければならないという問題がある。Furthermore, when the specific gravity of the reinforcing material and the matrix metal are significantly different in phase Jj4, it is difficult to produce a composite material in which the reinforcing material is uniformly dispersed in the matrix metal. Furthermore, in the compocasting method, since the molten matrix metal and the reinforcing material are mixed in a solid-liquid coexistence state, there is a problem in that the temperature of the molten matrix metal must be strictly controlled.
