"Aluminum composite material (FRM)" distributed at the 3rd Metal Forming Seminar held in Atami City on the 16th
As described in the brochure entitled "Formation of Composite Materials", the compocasting method has been known as one of the methods for producing composite materials when the reinforcing material is short fibers or particles. According to this compocasting method, a composite material with a smaller volume fraction of reinforcing material can be easily produced compared to other methods.

題がある。Problems to be Solved by the Invention However, in this composite casting method, the molten metal of the reinforcing material and the matrix metal must have good wettability with each other, and therefore, for example, when the matrix metal is an aluminum alloy, Conventionally, Mg and Ca have been added for the purpose of improving the wettability of reinforcing materials, and therefore there is a problem that the composition of the matrix metal is limited.

ばならないという問題がある。Further, when the specific gravity of the reinforcing material and the matrix metal are significantly different from each other, it is difficult to manufacture a composite material in which the reinforcing material is uniformly dispersed in the matrix metal. Furthermore, in the composite casting method, the molten matrix metal and 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.

The metal fluoride removes the oxide film on the surface of the reinforcing material and the molten metal of the matrix metal, thereby improving the wetting of the reinforcing material and the molten metal. Therefore, the reinforcing material gets well wetted with the molten metal of the 7-trix metal and blends well with the molten metal, and as the molten metal is stirred in this state, the reinforcing material is uniformly mixed with the molten metal. A composite material is produced which is uniformly dispersed in the matrix metal and has good adhesion to the matrix metal.

Composite materials can be manufactured easily and there is no need to strictly control the temperature of the molten matrix metal, so composite materials can be manufactured more easily and in a lower order than in the case of conventional composite casting methods. Can be done.

It can be manufactured easily and in descending order.

It is unnecessary to form a molded body containing a reinforcing material and fine pieces of metal fluoride, or a molded body containing a reinforcing material, fine pieces of metal, and fine pieces of metal fluoride.
