Description of the Related Art A clad plate in which dissimilar metals having different properties are combined has been used in a wide range of fields such as kitchenware, building materials, electronic components, and piping as materials having the advantages of the dissimilar metals. Above all, a stainless steel / aluminum clad plate obtained by combining stainless steel having excellent corrosion resistance and strength with aluminum having good thermal conductivity is widely used for electromagnetic cookers. However, 200-5
When a stainless steel / aluminum clad plate is used as a member that is exposed to a relatively low temperature range of 00 ° C. for a long time, a hard and brittle intermetallic compound layer is generated at the joint interface between the stainless steel and aluminum by mutual diffusion. For example, stainless steel (SUS430) / aluminum (A1100)
When the clad plate is heated to 500 ° C., Fe diffuses from the stainless steel side to the aluminum side at the joint interface of stainless steel / aluminum, and Al diffuses from the aluminum side to the stainless steel side.

In the example, the bonding strength is maintained at the bonding interface portion where there is no intermetallic compound 3. However, when the intermetallic compound 3 grows in a layered manner over the entire bonding interface (FIG. 1c), the intermetallic compound 3
Since it is hard and brittle, the bonding strength of the stainless steel / aluminum clad plate is almost lost. As a result, even a slight impact causes separation between the stainless steel 1 and the aluminum 2.

る効果がみられない。The present inventors have studied in detail the process of forming and growing intermetallic compounds generated when a stainless steel / aluminum clad plate is heated. As a result, it has been found that the formation and growth of the intermetallic compound is greatly affected by the components of stainless steel, particularly the C content and the Nb content.
The effects of the C content and the Nb content on the formation and growth of the intermetallic compound are presumed as follows. The intermetallic compound is
Interdiffusion between Fe and Al is promoted by heating at the stainless steel / aluminum joint interface, the concentration ratio of Fe and Al reaches the concentration at which an intermetallic compound is formed, and the energy (heating temperature) required for the formation of the intermetallic compound is reduced. Generate when added. At this time, if Nb is added to the stainless steel, C that promotes the interdiffusion reaction of Fe / Al is fixed as carbide NbC, and FeAl 3 , Fe 2 Al 5
, Etc., also increases. As a result, generation and growth of intermetallic compounds are suppressed, and the delamination resistance is improved. However, Ti, which acts to fix C as a carbide like Nb, has no effect of suppressing the formation of intermetallic compounds.

When a stainless steel / aluminum clad plate in which stainless steel containing 0.4% by mass of Nb was coated with aluminum (A1100) was heated under the same conditions, generation of an intermetallic compound was not detected. The effect of suppressing the formation and growth of the intermetallic compound by Nb is as follows.

On the other hand, in Test Nos. 1 and 10 to 12 using Nb-free stainless steel as a base material and Test No. 2 having a small Nb content, a metal compound layer having a maximum layer thickness of 30 μm was formed at the stainless steel / aluminum bonding interface. Grew in layers. Further, in Test Nos. 8 and 9 in which the C content was excessive even when Nb was contained in an amount of 0.2% by mass or more, a thick intermetallic compound layer was grown at the bonding interface. Further, even in Test Nos. 10 to 12 in which Ti having an action of fixing C like Nb was added,
An intermetallic compound layer was detected. As is clear from this comparison, the C / C content of the stainless steel used as the base material is regulated to not more than 0.03% by mass, and by adding 0.02% by mass or more of Nb, the mutual diffusion of Fe / Al is performed. It was confirmed that the reaction was suppressed, and a clad material free of delamination was obtained even when heated to a temperature range of 200 to 500 ° C. for a long time.
