Abstract

The invention discloses a three-layer titanium / aluminum / magnesium composite board. The three-layer composite board is formed by rolling a titanium alloy hot rolled steel plate, an aluminum alloy hot rolled steel plate and a magnesium alloy hot rolled steel plate together in a stacked mode. The manufacturing method of the composite board mainly comprises the steps that the TC4 titanium alloy plate, the 6061 aluminum alloy plate and the AZ31B magnesium alloy plate are selected and used, and the TC4 titanium alloy plate, the 6061 aluminum alloy plate and the AZ31B magnesium alloy plate are polished mechanically; the titanium alloy plate, the aluminum alloy plate and the magnesium alloy plate are placed in a stacked mode in sequence, and the titanium alloy plate, the aluminum alloy plate and the magnesium alloy plate are placed in a resistance furnace to be preheated for 6 min-10 min at the temperature ranging from 300 DEGC to 450 DEG C after one end of the titanium alloy plate, one end of the aluminum alloy plate and one end of the magnesium alloy plate are riveted; then the titanium alloy plate, the aluminum alloy plate and the magnesium alloy plate are conveyed onto a rolling mill immediately to be rolled, wherein the rolling speed ranges from 0.3m / s to 1.2m / s, and the hot milling deformation ranges from 25% to 50%. According to the three-layer titanium / aluminum / magnesium composite board and the manufacturing method of the three-layer titanium / aluminum / magnesium composite board, the technology is simple, cost is low, the production efficiency is high, and large-scale industrial production can be achieved easily; the interfaces of the manufactured three-layer titanium / aluminum / magnesium composite board are bonded tightly, and obvious micro-cavities and brittle intermetallic compounds are avoided; compared with an aluminum alloy plate with the same weight, the high-speed impact damage resistance of the composite board is improved by 50%.

Description

technical field [0001] The invention relates to the technical field of processing metal composite plates. Background technique [0002] With the continuous development of space technology, there are a large number of small debris in space, and the spacecraft cannot avoid it. The only effective measure is protection. The space environment effect and the level of protection largely determine the design level and service life of the spacecraft. The commonly used protective device for space debris in the world is to use the Whipple structure, which mainly includes a buffer layer, a back plate and related supporting structures. There is a certain distance between the buffer layer and the back plate. May fragment, melt and atomize, forming a cloud of debris. At present, the buffer layer material used in the world is mainly aluminum alloy, and its ability to resist the impact of debris needs to be improved urgently. If the aluminum alloy buffer layer in the Whipple structure is re...
