着する方法（接着法）、などが知られている。However, in order to meet the demands for weight reduction, some aluminum alloy composite structures have already been put into practical use for the purpose of using them as the above-mentioned parts, and their manufacturing technology is as follows:
) A method in which the iron-based alloy to be composited is set in a predetermined position in a mold, and then molten aluminum alloy is injected (casting method); 2) The iron-based alloy to be composited is press-fitted into the aluminum alloy at a predetermined position. 5) A method of joining the iron-based alloy to be composited to a predetermined position of the aluminum alloy using a brazing material (brazing method); 4) A method of joining the iron-based alloy to be composited to the aluminum alloy A method of adhering υ to a predetermined position using an adhesive (adhesion method) is known.

金と鉄系合金との熱膨張係数の差から両者の界面に空隙
が生じ引き巣などの欠陥が生じる等の点である。However, the following problems have been pointed out in each of the above conventional methods. In other words, composite structures manufactured using the casting method described in 1) cannot obtain high-strength materials due to restrictions on the composition of aluminum alloys, and due to the difference in thermal expansion coefficient between aluminum alloys and iron-based alloys. The problem is that voids are formed at the interface and defects such as cavities occur.
２）の圧入法による場合は、一定の圧入代をもった精度
の高い加工が必要となるが、圧入面（界面）の清浄を維
持しておくことが難かしく、圧入面が汚れる点である。When using the press-fitting method (2), highly accurate machining with a certain press-fitting allowance is required, but it is difficult to maintain the cleanliness of the press-fitting surface (interface), and the press-fitting surface becomes dirty. .

温での使用が難かしい点である。3) In brazing, there is no brazing material that can join aluminum alloys and iron-based alloys with sufficient bonding strength, and peeling occurs due to the difference in thermal expansion coefficients. With the adhesive method 4), it is difficult to obtain sufficient adhesive strength, and it is also difficult to use at high temperatures.

。Means for Solving Problem C] The present invention uses an aluminum alloy and an iron-based alloy that have a low thermal expansion coefficient of 7°C or less, and a metal or alloy that forms a eutectic with aluminum as an insert material. The present invention also provides an aluminum alloy composite structure according to claim (1), wherein the iron-based alloy has a hardness of 400 or more on the Vickers hardness scale. The structure is a second invention.

で４００以上であることが特に好ましい。One or more metals or alloys selected from the group consisting of Sn, Ti, and Mg are particularly preferred. Further, in the present invention, it is particularly preferable that the crystal grain and precipitate grain size of the aluminum alloy is 20 μm or less, and the hardness of the iron-based alloy is 400 or more on the Vickers hardness scale.

であれば問題がないからである。In the present invention, the aluminum alloy is 19X10''
Use a material with a low coefficient of thermal expansion of less than 30°F.This is because if the difference in coefficient of thermal expansion is too large with that of the material to be composited, it will desorb when subjected to thermal cycles. This is because there is no problem as long as the temperature is below 19X10-'C, which is the limit for aluminum alloys.
また本発明におけるアルミニウム合金は結晶粒および析
出粒サイズが２０μ惰以下のものを用いることが好まし

構造体が内燃機関の部品等に用いられる場合、従来法の
鋳造法等によって製造されるアルミニウム合金では強度
が不足する。The aluminum alloy requires a certain level of strength and rigidity in order to prevent detachment of the composite body or deformation of the aluminum itself when subjected to external frictional impact. Particularly when such an aluminum alloy composite structure is used for internal combustion engine parts, aluminum alloys manufactured by conventional casting methods lack strength.
そこで本発明においては粉末冶金法により製造した、結
晶粒および析出粒サイズが２０μへ以下のアルミニウム
合金であることが好ましい。Therefore, in the present invention, it is preferable to use an aluminum alloy manufactured by a powder metallurgy method and having a crystal grain and precipitate grain size of 20 μm or less.

合金元素を添加することが可能であシ、その結果結晶粒
が微細化し、かつ偏析のない均一組織の高強度アルミニ
ウｉ合金が得られるからである。The reason for this is that according to the powder metallurgy method, it is possible to add alloying elements to supersaturation by rapid cooling, and as a result, grains become finer and a high-strength aluminum alloy with a uniform structure without segregation can be obtained. It is from.

めである。In addition, in this powder metallurgy method, the cooling rate of the raw material powder is 10
2°C/sec or more is preferable, and 103°C/BeQ or more is particularly preferable. This is because if the temperature is below 103°C/880°C, a sufficient quenching effect cannot be obtained, and crystal refinement and solid solution strengthening cannot be achieved.

耗性が著るしく劣化するからである。Examples of the iron-based alloy in the present invention include carbon steel, carburized and quenched materials, high-speed steel, chilled cast iron, EIUH-5, etc., and it is preferable that the hardness thereof is 400 or more on Guitzkaas hardness. This is because the composite structure of the present invention needs to have excellent abrasion resistance, and if the Vickers hardness is less than 400, the surface pressure strength will be low and the abrasion resistance will deteriorate significantly. It is.

なくとも一方と超音波接合されていることが好ましい。Furthermore, in the present invention, it is preferable that the metal or alloy that forms a eutectic with aluminum is ultrasonically bonded to at least one of an aluminum alloy and an iron-based alloy.
この理由は次のとおりである。The reason for this is as follows.

壊され微視的く凹凸が平滑化される。Ultrasonic bonding is a method in which the material to be welded is supported between two welding tips under a light load, ultrasonic waves are applied while applying pressure, and the vibrations of the ultrasonic waves are used to bond the material. When ultrasonic bonding is used to obtain a composite structure using an aluminum alloy and an aluminum alloy, the ultrasonic vibration causes slippage υ at the contact surface between the two alloys, destroying the adsorption layer and oxide film on the surface and causing slight damage. Visually unevenness is smoothed out.

がある。Also, a clean metal matrix appears, and the thermal diffusion of atoms becomes active due to the temperature increase due to plastic flow and frictional heat, and the atoms stick together in atomic size, rearrangement of atoms occurs and bonding to the gold is achieved. . However, in the case of dissimilar metals with a large difference in hardness, or in the case of two alloys having different thicknesses, joining may be difficult.

で良好な密着を得る。Specifically, the metal or alloy is inserted as a foil between the iron-based alloy and the aluminum alloy, or the metal or alloy is coated on the joint surface of at least one of the iron-based alloy or the aluminum alloy, and then ultrasonic bonding is performed. This significantly promotes bonding and provides good adhesion in a short time.

得られた。The thickness of this insert material is preferably 5 to 50μ, because if it is too thin, the effect of promoting bonding will not be seen, and if it is too thick, there will be too many layers of the insert material, which will lead to deterioration of bonding strength. Good bonding strength was obtained within this thickness range.
