Abstract

The invention relates to a preparation method for an interface space metallurgy bonded aluminum alloy-aluminum-steel transition joint. The preparation method specifically comprises the following steps: 1) processing a corrugated surface of a to-be-compounded steel plate and a corrugated surface of an aluminum alloy board, and processing the to-be-compounded steel plate, an aluminum board and a to-be-compounded surface of the aluminum alloy board; 2) assembling the to-be-compounded steel plate, the aluminum board and the aluminum alloy board to form assembly blank; 3) compressing and compounding the assembly blank on a press, thereby preparing a primarily bonded aluminum alloy-aluminum-steel composite board; 4) placing the primarily bonded aluminum alloy-aluminum-steel composite board on ahigh-temperature pressure tester, performing micro-pressure thermal diffusion treatment, and finally forming a space metallurgy bonded aluminum alloy-aluminum-steel composite board; and 5) performingedge-cutting treatment on the space metallurgy bonded aluminum alloy-aluminum-steel composite board to obtain the aluminum alloy-aluminum-steel transition joint. The preparation method realizes interface regular-space metallurgical bonding, so that the product is stable in performance, and is reduced in thermal sensitivity of interface strength after being subjected to micro-pressure diffusion annealing.

Description

technical field [0001] The invention belongs to the technical field of preparation of metal layered composite materials, and in particular relates to a preparation method of an aluminum alloy-aluminum-steel transition joint combined with interface space metallurgy. Background technique [0002] With the transformation of shipbuilding industry technology, the development concept of high efficiency and environmental protection has prompted the shipbuilding industry to continuously innovate technology and accelerate the application and development of new shipbuilding materials, processes and equipment. Due to the advantages of small specific gravity, high specific strength, non-magnetic, weldable, easy to form, no low-temperature brittleness, and seawater corrosion resistance, aluminum and aluminum alloy materials are widely used in ship superstructures, outfitting parts, and deckhouses. The weight of the ship itself is greatly reduced, the carrying capacity of the ship is incr...
