Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] As shown in Figure 1, it is a structural schematic diagram of a metastable Cu-based and Ni-based double-layer alloy composite foil prepared by the device of the present invention. The chemical composition of the Cu-based alloy layer is 7% to 20% according to the weight percentage Sn, and B is 0.5 % to 1.0%, and the rest is Cu; the chemical composition of the Ni-based alloy layer is 5% to 9% of Si, 0.5% to 1.0% of B, and the rest is Ni.

[0015] As shown in FIG. 2 , it is a schematic structural diagram of a prior art device. The crucible 2 is placed in the high-frequency induction coil 6, and the high-frequency induction coil 6 is located directly above the roller 8. The motor uses a high-speed motor with adjustable angular velocity to drive the roller 8 to rotate, and the roller surface line speed is controlled at different speeds. It...

Abstract

The invention discloses a device used for preparing a double-ply metal-alloy foil with a Cu base and a Ni base in a metastable state, which comprises a vacuum case. A wall board of the vacuum case is provided with a vacuum pump and a rotor driven by a motor, the upper surface of the vacuum case is connected with a small vacuum case which is provided with an argon inlet, the bottom of the small vacuum case is connected with a crucible which is arranged in a high-frequency induction coil, an inner chamber of the crucible is separated from the middle portion and is divided into two smelting chambers, the bottom of each smelting chamber is opened and provided with a nozzle, the high-frequency induction coil is arranged on the upper side of the rotor, and the lateral edge of the vacuum case is provided with a collecting chamber. The device of the invention is capable of accomplishing the preparation of the double-ply metal-alloy foil with a Cu base and a Ni base in a metastable state, and has the advantages of simple process, convenient operation, and being convenient for wide application.

Description

technical field [0001] The invention belongs to the technical field of material manufacture, and relates to a device for preparing a metastable Cu-based and Ni-based double-layer alloy composite foil. Background technique [0002] At present, a large number of connection structures of new materials and dissimilar materials are used, and the connection structure of copper alloy and stainless steel has become an important component. However, the welding of copper and stainless steel belongs to the welding of dissimilar metals. The physical properties of the two are very different. When the two are welded, a lot of stress is bound to be generated. During the welding process, eutectics and brittle compounds with low melting points will be formed. The area is prone to thermal cracks, and the welding performance of copper and stainless steel is poor. Transitional liquid phase diffusion welding is a welding method in which the intermediate layer is pre-welded before welding, and t...
