Abstract

The invention discloses a preparation method of a pulse current assisted rolling difficult / easy-deformable metal composite plate. The composite plate includes a difficult-deformable metal plate and an easily-deformable metal plate; After pre-rolling assisted by pulse current with small corrugation, the billets are put into a rolling mill equipped with a pulse power supply device for flat roll rolling to obtain a composite plate. The preparation method of the pulse current assisted rolling difficult / easy-to-deform metal disclosed in the present invention utilizes the tip discharge effect and the electroplastic effect to improve the plasticity of the two kinds of metal plates by discharging in the tiny gaps of the metal plates during rolling. Deformation resistance is reduced and residual stresses are relieved, resulting in a metallurgical bond. The preparation method has the advantages of low rolling temperature, less interface brittle compounds, significantly improved microstructure, and the prepared material has good plate shape, high composite strength and good interface bonding performance.

Description

technical field [0001] The invention relates to a preparation method of a metal composite plate, in particular to a preparation method of a pulse current assisted rolling difficult / easy-to-deform metal composite plate. Background technique [0002] Refractory metals have complex chemical composition and high content of alloying elements, and have the advantages of anti-oxidation, corrosion resistance and fatigue resistance, but they have high deformation resistance, poor plasticity and severe hardening during processing. Deformable metals have the advantages of light weight and easy processing, but their processing technology has poor rigidity and large amount of material removal. Difficult / easy-to-deform metal composite panels combine the advantages of both and have excellent comprehensive performance. They are widely used in aerospace, automotive, light industry and other fields. [0003] At present, the preparation methods of metal clad plates mainly include explosive cl...
