Austenitic stainless steel composite materials are in relatively high demand, for example for use as oil cooler pans in automatic cars and electronic materials, but they are expensive materials and material costs are too high for general use. There are many problems with this. Note that, although the present invention will be explained below by taking a composite plate material as an example, the present invention is not necessarily limited to composite plate materials. The same applies to the cladding wire.

Cold brushing is performed at room temperature up to about 50° C. for the purpose of surface activation and distortion, and then cold welding is performed by cold rolling at a reduction rate of 60% or more. however,
In such conventional methods, excessive brushing in an attempt to achieve sufficient surface activation may cause scratches on the material and cause deterioration of mechanical properties, and it is difficult to remove a small amount of oxide film formed during brushing. This is difficult, and this remains at the bonding interface and appears as a deterioration in bonding strength. For example, when used as a material for electronic components, performance deterioration is inevitable. Furthermore, in order to ensure a rolling reduction of 60% or more, a very large rolling load is required, and therefore the width dimension of the press-welded material is usually 300 mm 2 and maximum 600 mm 2 . By the way, for such composite materials, the processing cost that accounts for the material cost, that is, the processing cost for compounding, is large, and there is a strong demand for its reduction.

A specific object of the present invention is to provide an inexpensive method of manufacturing a copper/austenitic stainless steel composite material that allows effective bonding with less rolling load.

【課題を解決するための手段】本発明者らは、かかる課
題を解決すべく、従来技術の内容について再検討を重ね
たところ、従来はむしろ表面酸化が生じるから接合強度
が劣化するとされてきた加熱状態での接合について着目
して、種々検討を重ね、次のような知見を得た。
（１） 銅はステンレス鋼に比較して酸化し易いが、１
００ ℃以下の加熱では例えば１時間加熱しても接合を
阻害するような厚膜の酸化皮膜の生成はしない。しかし
１５０ ℃を越えると接合を阻止する酸化皮膜が生成す
る。[Means for Solving the Problem] In order to solve the problem, the present inventors repeatedly reviewed the contents of the conventional technology and found that in the past, it was thought that surface oxidation rather deteriorated the bonding strength. Focusing on bonding under heating, we conducted various studies and obtained the following knowledge. (1) Copper is more easily oxidized than stainless steel, but 1
When heated at 00° C. or lower, for example, even after heating for 1 hour, a thick oxide film that inhibits bonding is not generated. However, if the temperature exceeds 150°C, an oxide film is formed that prevents bonding.
【０００６】（２） 加熱後にブラッシングを行えば、
上述のように１５０ ℃を越えて加熱したときに生成し

、銅の場合、表面が硬くなり内部は軟らかい状態となり
、この加工硬化した表面に割れが多数生成してそこから
内部の新生面が露出し、接合時の接合力が増大すること
。(2) If brushing is performed after heating,
As mentioned above, the oxide film formed when heated above 150°C can be removed, and warm brushing can be completed in a short time, and the activity of the resulting surface is increased. (3) When brushing is performed at temperatures below 200 degrees Celsius, the surface of copper becomes hard and the inside becomes soft, and many cracks form on this work-hardened surface, through which new internal surfaces are exposed. Increased bonding force during bonding.

This means that, in fact, such a method makes it possible to manufacture a wide composite material with a width of 1 meter, which was previously impossible. (5) Furthermore, if the stainless steel plate is also heated, a significant improvement in joint strength can be seen due to the synergistic effect with warm brushing. (6) In addition, if heat treatment is performed after bonding, even if the peel strength is not very high, the bond will be completely adhered, but if the peel strength due to rolling bonding is low, some parts may peel off during winding, or they may peel off due to differences in thermal expansion during cooling or heating. Therefore, the peel strength before heat treatment is as high as possible, preferably ≧1.

, Tsus: A method for manufacturing a copper/stainless steel composite material characterized by rolling and joining at a temperature higher than the temperature of stainless steel (° C.). In a preferred embodiment of the present invention, the stainless steel is an austenitic stainless steel, and the joining surface is heated to a temperature of 200 to 400% prior to warm joining.
Heat to ℃. Note that the composite material obtained by the present invention includes not only plate materials but also foils, thin plate clads, clad wires, and the like. In the case of plate materials, there are no particular restrictions on the thickness of the copper plate that is the joining material and the thickness of the stainless steel plate that is the base material, which is usually austenitic stainless steel, and should be determined as appropriate based on the rolling reduction rate and the required thickness of the target composite material. Bye. Sufficient joining can be achieved with a rolling reduction ratio of 20% or more, but if the rolling reduction ratio is too large, the rolling load required to achieve this becomes excessive, making it impossible to roll wide materials, so generally a rolling reduction of 20 to 40% is required. It is preferable to set conditions so that rolling joining is performed at a certain rolling reduction rate.

FIG. 1 is a process diagram of the manufacturing method according to the present invention. First, a copper plate is degreased in a degreasing step 1, heated through a heating step 2 of 50 to 200°C, and then warm brushed in a brushing step 3. to activate the joint surface. On the other hand, an austenitic stainless steel plate is also subjected to a similar process, and after degreasing, according to a preferred embodiment, it is heated and then warm brushed. Here, warm brushing is carried out for the purpose of surface activation and application of a work-hardened layer, and refers to the operation of grinding the board surface with a wire brush, etc., and the temperature at the time of brushing is 50 to 2
The only difference is that the temperature is 00° C., but the same operation as conventional cold brushing may be performed, and there is no limitation in that respect.

得られる。[0010] Immediately after warm brushing, warm bonding is performed in warm rolling step 4. It is sufficient that the temperature during warm bonding is 50 to 200°C, which is the same as the heating temperature of the copper plate, but a higher temperature within the range of 100 to 200°C is usually preferable. If the stainless steel plates are austenitic stainless steel, warm joining can be performed more efficiently by heating the joining surfaces to 200 to 400°C. Warm rolling has a reduction rate of at least 20%, generally 20-40
It is preferable to use a rolling reduction ratio of %. According to the present invention, even with such a small rolling reduction ratio, good joining is possible, and therefore the rolling load required for this is also small, and as a result,
A wide rolled composite material is obtained. In particular, according to the present invention, a wide material with a width of 1 m, which has not been realized in the past, can be obtained.

The heat treatment conditions at this time are 600 to 1040℃ x 0.01 to 15 hours, and a completely adhered composite material can be obtained, and a particularly wide material can be obtained, which greatly contributes to reducing manufacturing costs. be able to. However, since the peel strength of the composite material rolled and bonded according to the present invention is 1 kgf/mm2 or more, it is possible to roll it up as it is after rolling and bonding, or to perform processing such as pressing and then heat treatment to completely bond the material. It can also be used as a thing.
