Explosive welding forming method for magnesia-alumina-titanium alloy composite board

Abstract

The invention relates to an explosive welding forming method for a magnesia-alumina-titanium alloy composite board, which is performed aiming at the performance requirements of a magnesium alloy board, an aluminum alloy board and a titanium alloy board; an ammonium nitrate fuel oil mixture is adopted for performing remote instant explosive welding forming on a sand substrate on the ground; the welding forming method is quick in speed, firm in interface bonding, good in interfacial shear strength and high in boding rate; the magnesia-alumina-titanium alloy composite board achieves the shear strength of 150MPa, the explosive welding bonding rate is 96.8%, the controllability is good, the welding process is safe and reliable, and thereby the explosive welding forming method is a reliable and effectively method for preparing the magnesia-alumina-titanium alloy composite board.

Description

technical field

[0001] The invention relates to an explosive welding forming method of a magnesium-aluminum-titanium alloy composite plate, which belongs to the technical field of processing and manufacturing non-ferrous metal plate materials. Background technique

[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 sco...
