A method for producing a metal-based composite feed in which the matrix is a metal selected from the group consisting of Mg alloys and Mg alloys, wherein an inorganic reinforcing material and a matrix are placed on a support having a predetermined shape, the surface of which is made of carbon or graphite. forming a porous molded body containing a metal and a metal fluoride that have excellent wettability with respect to the molten metal, and bringing at least a portion of the molded body into contact with the molten metal of the matrix to substantially pressurize the molten metal. This is achieved by a method for producing a metal matrix composite feed, which comprises infiltrating the metal-based composite feed into the molded body, solidifying the feed, and then removing the support.
発明の作用及び効果
無機質の強化材と金属と金属フッ化物とを含む多孔質の
成形体の少くとも一部がマトリックス金属の溶湯と接触
せしめられると、溶湯は金属を伝って成形体中へ浸透し
、金属フッ化物はマトリックス金属の溶湯及び金属の酸
化膜を除去して強化材に対する溶湯の濡れを改善する。Functions and Effects of the Invention When at least a portion of a porous molded body containing an inorganic reinforcing material, a metal, and a metal fluoride is brought into contact with the molten metal of the matrix metal, the molten metal permeates through the metal and into the molded body. However, the metal fluoride improves wetting of the molten metal to the reinforcing material by removing the molten metal of the matrix metal and the oxide film of the metal.
またマトリックス金属の溶湯及び金属は互いに反応する
ことによって発熱し、その熱によって溶湯及び強化材か
加熱され、これにより溶湯の成形体中への浸透性及び強
化材の濡れ性が向上され、これによりマトリックス金属
の溶湯が成形体全体に良好に浸透して行く。In addition, the molten matrix metal and the metal generate heat by reacting with each other, and the heat heats the molten metal and the reinforcing material, which improves the permeability of the molten metal into the compact and the wettability of the reinforcing material. The molten metal of the matrix metal satisfactorily penetrates into the entire molded body.
また炭素や黒鉛は軽金属の溶湯に対し殆ど濡れないので
、軽金属の溶湯が凝固した後にその凝固体より支持体を
容易に除去することができる。Further, since carbon and graphite hardly wet the molten light metal, the support can be easily removed from the solidified body after the molten light metal is solidified.

易に且能率よく形成することかできる。Therefore, according to the method of the present invention, a porous molded body containing reinforcement (a), metal, and metal fluoride is formed in a predetermined shape and size on a support of a predetermined shape, and the molded body is placed in a matrix. When brought into contact with molten metal, the molten matrix metal quickly permeates throughout the molded body, and the molded body is maintained in a predetermined shape and size by the support until the molten matrix metal solidifies. Since the support can be easily removed from the solidified body after the molten matrix metal has solidified, it is possible to easily and efficiently produce a composite material made of a light metal reinforced with a reinforcing material up to the surface in a predetermined shape and size. Can be well formed.
またマトリックス金属の溶湯を加圧したり所定の製品形

実質的に所定の形状及び寸法の複合材料を能率よく低数
に製造することができる。Furthermore, there is no need for a mold to pressurize the molten matrix metal or define a predetermined product shape, and a large amount of the matrix metal solidifies in parts of the mold other than the composite feed, as in the case of high-pressure casting. Therefore, it is possible to efficiently manufacture a small number of composite materials having a substantially predetermined shape and size with a very high yield compared to conventional methods for manufacturing composite materials.

By forming a long molded body on a body, a long composite material can be manufactured into a container.

０５９６以上に設定される。According to the results of experimental research conducted by the inventors of the present application, if the molded body contains metal and metal fluoride, the permeability of the molten matrix metal into the molded body can be improved. However, the weight ratio of metal to reinforcing material is 296 or more, and the weight ratio of metal fluoride to reinforcing material is 0.
When the amount is 0.03% or more, particularly 0.05% or more, the molten matrix metal can be well penetrated into the molded body. According to another detailed feature of the invention, therefore:
The amount of metal in the compact is 2% by weight relative to the reinforcement.
The amount of metal fluoride in the molded body is set to be 0.03% or more, preferably 0.03% or more in terms of weight ratio to the reinforcing material.

If the total volume fraction of the reinforcing material, metal, and metal fluoride in the molded body is too low, or conversely too high, it will be difficult to allow the molten metal of the matrix metal to satisfactorily penetrate into the molded body. According to yet another detailed feature of the invention, the total volume fraction of reinforcing material, metal and metal fluoride in the compact is therefore set between 5 and 80%, preferably between 6 and 80%. .

Even if the volume fraction of the metal contained in the molded body is high, the molten matrix metal can be penetrated into the molded body well, but the larger the amount of metal, the lower the volume fraction of the reinforcing material. Depending on the type, the composition of the matrix metal may change significantly. Therefore, according to yet another detailed feature of the invention, the volume fraction of metal in the molded body is set to 80% or less, preferably 75% or less.
