[0002] Magnesium alloy has the characteristics of light specific gravity, high specific strength, easy recycling, and rich reserves of resources. It is a green engineering structural material and has a wide range of application values ​​in the fields of automobile, aerospace, and electronics industries. However, magnesium alloys have poor corrosion resistance, strength, The low hardness has greatly limited the application of magnesium alloys; in order to improve the strength, hardness and corrosion resistance of magnesium alloys and broaden their application fields, magnesium alloys are often combined with other metals with good corrosion resistance and high strength. , made of composite panels to expand its application range

[0003] At present, there are two ways to process the magnesium alloy clad plate, one is explosive welding, and the other is rolling. The explosive welding process is to push the clad plate to act on the substrate through the instantaneous high pressure and high temperature of the explosive detonation wave, so that It achieves solid-phase connection and metallurgical combination, among which, explosive welding is suitable for the connection of the same or dissimilar metals; the size and shape specifications of the explosive composite plate are not limited by the equipment; the explosively formed composite material has high bonding strength and reproducibility Processing performance, but there are still many disadvantages in the explosive welding forming process, such as uniformity, bonding strength, and safety performance need to be further improved
