〔産業上の利用分野〕
本発明は金属複合材料、特に軽量、耐熱性および耐摩耗
性が要求される部品、例えば内燃機関のピストンやコネ
クティングロンドの製作に適した材料の製造方法に関す
るものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to metal composite materials, particularly materials suitable for manufacturing parts that require light weight, heat resistance, and wear resistance, such as internal combustion engine pistons and connecting rods. The present invention relates to a manufacturing method.
従来、金属複合材料の製造方法としては、補強材の繊維

し、押出すか、または圧延を行った後に焼結するのか一
般的だった。Conventionally, the common method for manufacturing metal composite materials has been to mix reinforcing material fibers, fine wires, or powder with matrix metal powder, extrude it, or roll it and then sinter it.
また、従来補強材とマトリックス金属との混合粉末の単

繊維を用いての単純加圧成形により、特性にバラツキの
ない均一な材料を得る方法が提案されている（特開昭６
１−２７２３０１号公報参照）。In addition, it has been difficult to obtain stable properties with conventional composite materials formed by simply pressing a mixed powder of reinforcing material and matrix metal, but in recent years, simple pressure forming using thin short fibers as the matrix metal has been difficult. proposed a method for obtaining a uniform material with no variation in properties (Japanese Unexamined Patent Publication No. 6
1-272301).
しかしながら、上記従来の単純加圧による方法は、粉末
表面に吸着しているガスが材料内部に留まって成形され
てしまうため、ブリスタ等の欠陥が発生するという問題
がある。However, the conventional method using simple pressurization has a problem in that the gas adsorbed on the powder surface remains inside the material and is molded, resulting in defects such as blisters.
また、従来の押出し、または圧延する方法は、安定した
特性が得られるものの、太い径を有する素材が得られず
、そのため大型部品例えばビスＩ−ン等の製造に使用で
きる材料を得ることはできなかった。In addition, although conventional extrusion or rolling methods can provide stable properties, they cannot produce materials with large diameters, and therefore cannot produce materials that can be used to manufacture large parts such as screw links. There wasn't.
本発明は、このような問題点を考慮してなされたもので
あり、その目的とするところは、単純加圧により固化可
能な金属複合材料の製造方法を提供することである。The present invention has been made in consideration of such problems, and its purpose is to provide a method for manufacturing a metal composite material that can be solidified by simple pressurization.

本発明の金属複合材料の製造方法は、

℃の温度で本成形することを特徴とする。(Means for Solving the Problems) The method for producing a metal composite material of the present invention includes mixing and pulverizing an aluminum alloy fibrous powder and a ceramic powder using a vibrating mill, and pulverizing the obtained mixed powder into one part.
The aluminum alloy is preformed at a temperature of 00 to 300°C, and then the solidus of the aluminum alloy is
It is characterized by main forming at a temperature of ℃.
上記のように、本発明の方法は、混合粉末を予備成形お
よび本成形からなる２段階で固化する方法である。As described above, the method of the present invention is a method in which mixed powder is solidified in two stages consisting of preforming and main molding.
本発明における金属複合材料のマトリックス金属は、ア
ルミニウム合金の繊維状粉末である。The matrix metal of the metal composite material in the present invention is a fibrous powder of aluminum alloy.
該繊維状粉末は、びびり切削法により製造することがで

。また、マトリックス組成としては、■を含有するもの
か、セラミック粉末との結合上好ましい。The fibrous powder can be produced by a chatter cutting method, and preferably has a diameter of 100 μm or less and a length of 2 to 5 mm. This is because when the diameter exceeds 100 μm, the dispersion distance of the ceramic powder becomes 100 μm or more, which reduces the improvement in properties due to compounding, when the length exceeds 5 mm, the mixing efficiency in the vibration mill decreases, and when the length is less than 2 mm, the dispersion distance of the ceramic powder becomes more than 100 μm, and when the length exceeds 5 mm, the mixing efficiency in the vibration mill decreases. This is due to decreased workability during processing such as cleaning and drying. Further, as for the matrix composition, one containing (1) is preferable in terms of bonding with the ceramic powder.
また、前記セラミック４５〕末としては、４μ以下の、
Ａ１□０３、ＳＩＣまたはＳｉＯ□粉末が好ましく、特
にＳｉＣかマトリックスとの結合に優れるため好ましい
。In addition, the ceramic 45] powder has a particle size of 4μ or less,
A1□03, SIC, or SiO□ powder is preferable, and SiC is particularly preferable because it has excellent bonding with the matrix.
本発明の方法において、前記繊維状粉末とセラミンク粉
末との混合は、振動ミルによって混合粉砕する。混合粉
砕には他に、アトマイシング法等があるが、これは前記
振動ミルによるよりもセラミンク粉末のマＩ・リノクス
粉末への混練効果が低いため、採用しなかった。In the method of the present invention, the fibrous powder and the ceramic powder are mixed and ground using a vibrating mill. Other methods of mixing and pulverization include the atomizing method, but this method was not adopted because it has a lower kneading effect on the ceramic linox powder than the vibrating mill.
前記混合粉末の予備成形は、１００ないし３００℃の温

している水萎気や酸素等のガスの離脱が十分に行われず
、該吸着ガスを含むまま本成形されることになり、次の
本成形により粉末間の結合が十分に起こらず、また３０
０°Ｃを越えると、予備成形を行わずに本成形を行った
時と同じく、内部にガスが閉じ込められ、これも結合が
十分に起こらないことによる。The mixed powder is preformed at a temperature of 100 to 300°C. This is because if the temperature is lower than 100°C, gases such as water and oxygen adsorbed on the powder surface will not be released sufficiently, and the main molding will be carried out with the adsorbed gases still contained, and the next main molding will be carried out. Bonding between powders does not occur sufficiently, and 30
If the temperature exceeds 0°C, gas will be trapped inside, as in the case of main molding without preforming, and this is also due to insufficient bonding.
また、前記予備成形は、通常３ ｔｏｎ／ｃｍ２程度で
加圧し、前記吸着ガスを離脱させつつ、加圧することが
必要である。Further, in the preforming, it is usually necessary to pressurize at about 3 ton/cm 2 and pressurize while removing the adsorbed gas.
次に本成形はマトリックス粒子である前記アルミニウム
合金の固相線ないし固相線−ト４０ ℃の温度で行う。Next, the main forming is carried out at a temperature of 40° C. between the solidus line and the solidus line of the aluminum alloy, which is the matrix particles.

結合が十分に起こらず、一方面相線＋４０°Ｃを越える
と、液相生成によりブリスタ状に膨れが生じ、該ブリス
タが本成形後も消滅することなく異常組織として残留す
るため、十分な強度を得ることができないことによる。This is because below the solidus temperature, sufficient bonding between matrix particles does not occur, and when the temperature exceeds +40°C on one side, liquid phase formation causes blister-like swelling, and the blister remains after the main molding. This is due to the fact that sufficient strength cannot be obtained because the tissue remains as abnormal tissue without disappearing.

可能となったものである。The method for producing a metal composite material of the present invention is as follows: ma) IJ socks are used to produce aluminum alloy fibrous powder, and ceramic powder is used as a reinforcing material. This made it possible to mold the material.

が十分に行われる。In addition, in this method, this simple pressurization is performed in two stages, that is, preforming and main forming, so the main forming is performed after the gas adsorbed on the surface of the powder is expelled by the preforming. This results in sufficient bonding between matrix particles.
