Embodiment 1
[0030] Select aluminum alloy (AA6061), magnesium alloy (AZ31) and titanium alloy plates (TC4) with a thickness of 1mm, 2.2mm and 0.5mm, and the size specification is 500mm×350mm. Annealing pretreatments were performed before rolling (Al alloy AA6061, annealed at 450°C for 1h; magnesium alloy AZ31, annealed at 350°C for 0.5h; titanium alloy TC4 at 500°C for 1h).
[0031] Use a stainless steel brush to polish the surface of the annealed plate, then rinse it with clean water and dry it.
[0032] The surface-treated slabs are stacked in the order of aluminum, magnesium, and titanium, and the ends are riveted and fixed.
[0033] The thickness of the composite billet is about 3.6mm, put it into a heating furnace and heat it for 10 minutes at a heating temperature of 350°C, then take it out for hot rolling and compounding, and the reduction is about 30%.

Abstract
The invention discloses a rolling compounding method for an aluminum/magnesium/titanium three-layer composite plate. The characteristics of high strength of titanium alloy, low melting point and good vibration reducing performance of magnesium alloy, good plasticity and space adaptation of the aluminum alloy, and the like, are utilized and the excellent characteristics of respective component metals are combined by the aluminum/magnesium/titanium three-layer composite plate provided by the invention, so that the high-speed impact damage resisting property which the component metals do not own is acquired. Through the control on the ratio and interface of the aluminum alloy, the magnesium alloy and titanium alloy, the degree of fragmentation, melting and atomizing of shred cloud after the buffer composite plate is subjected to high-speed impact is changed and adjusted, so that the form of the shred cloud is changed, the degree of impact damage to a backplate is reduced, and the high-speed impact damage resisting property is increased. The aluminum/magnesium/titanium three-layer composite plate is applied to an outer layer buffer plate in an outer layer protecting structure of an aerospace vehicle and can be used for replacing a traditional single aluminum alloy material. The space environmental effect and protecting level of the space vehicle are increased; the design level of the space vehicle are greatly promoted, and the service life of the space vehicle are greatly prolonged.
Description
technical field [0001] The invention relates to the technical field of metal processing, in particular to the field of metal composite plate manufacturing. Background technique [0002] Metal layered composite material is a new type of material prepared by using composite technology to make two or more metals with different physical, chemical and mechanical properties realize firm metallurgical bonding at the interface. Each component of the layered composite material maintains its relative independence, but it is not a simple superposition of the component materials, so its physical, chemical and mechanical properties are much superior to those of a single metal, which is the so-called composite effect, so it is required to resist wear. , corrosion resistance, impact resistance and many other special fields have been widely used. [0003] In existing aerospace vehicles, aluminum alloy materials (for example: AA6061) are usually used as protective materials. Its anti-high-...
