BACKGROUND OF THE INVENTION The present invention relates to a hot isostatic pressing method (H

2. Description of the Related Art Conventionally, a hot isostatic pressing (HIP) method has been used as a method for manufacturing diffusion-bonded composite pipes, rods, and composites having a special shape.

なった。
[0003] In this HIP, since the pressure is uniformly applied to the entire surface, the structure becomes uniform and a high-quality molded product can be obtained. Utilization of the diffusion bonding composite body has been attempted by utilizing the characteristics of HIP utilizing this static pressure.

【0004】複合体の製造に際して、圧延、鍛造、押出

やすく、拡散接合に及ぼす影響は少ない。
When a composite is manufactured by dynamic pressure bonding such as pressure bonding by rolling, forging, or extrusion, even if an oxide film is present at the bonding interface, it will not move. Force acts on the interface and the oxide film is easily destroyed, and the influence on diffusion bonding is small.

However, when this HIP is applied and pressurized at a high temperature, a static isotropic pressure acts on each joint surface of each element unit, so that it exists at the joint interface of each element unit. The oxide film is not easily broken, and the oxide film hinders diffusion bonding due to pressure.

Therefore, in diffusion bonding by HIP, it is necessary to perform cleaning such as removal of an oxide film on each bonding surface of each element in advance, which not only requires extra labor, but also However, it is difficult to completely remove the oxide film and form a uniform active surface. In particular, when an active metal such as aluminum or titanium is used as a joining member, the oxide film formed on the surface is strong and stable, so it is necessary to remove the oxide film by mechanical or chemical means in advance. Even if it does, it is impossible to obtain a sound diffusion bonding interface.

As a diffusion bonding method using aluminum as a bonding element member by dynamic pressure, Japanese Patent Publication No. 5-6203
According to Japanese Patent Publication No. 4 and Japanese Patent Publication No. 6-49618, a single-layer insert material made of an aluminum alloy containing magnesium and lithium is interposed at the joint interface and heated and pressed at the diffusion temperature of magnesium and lithium. It is disclosed that a composite having excellent bonding strength can be obtained.

However, when such a joining method with the interposition of an insert material is applied to the diffusion joining by HIP, the existence of the joining layer between the joining elements becomes conspicuous and there is a possibility that the portion becomes heterogeneous. . Moreover, the number of steps is increased by interposing the insert material, which leads to a decrease in production efficiency and an increase in cost.

Further, since the joining interface is often limited to a simple shape such as a flat surface due to the interposition of the insert material, it may be difficult to apply it to a complicated joining interface including a phase or the like. There is a problem that the degree of freedom of is small.

As a solid-phase joining method without interposing an insert material, Japanese Patent Publication No. 60-133987 discloses a clean new surface by removing the oxide film on the surface of the other joining material by the edge of one joining material. Forming and joining is disclosed. However, when bonding is performed while heating in the air, there is a possibility that the oxide film of one of the bonding materials that forms the edge may remain, or oxide may be entrapped in the bonding interface due to cutting, and oxidation at the bonding interface may occur. Complete removal of objects is impossible.
