Problems solved by technology

[0004] However, when the three alloys of titanium, aluminum, and magnesium are combined, because the performance of most titanium alloys is significantly better than that of magnesium alloys and aluminum alloys, especially the high yield strength and large deformation resistance, resulting in the failure of the titanium alloy when the three are rolled and combined. The deformation is very small, which affects the composite effect between titanium / aluminum and titanium / magnesium, making the interface strength lower

Abstract

The invention discloses a rolling preparing method of a tooth-shaped junction surface of a titanium / aluminum / magnesium composite board. According to the method, an aluminum alloy sheet serves as a middle transition layer, finally, titanium alloy and aluminum alloy boards are rolled and composited under the high temperature, a composite face is a tooth-shaped face, a magnesium alloy board is rolledunder the high temperature, the face to be composited is the tooth-shaped face, and the tooth-shaped faces of the titanium / aluminum composite board and the magnesium alloy board are engaged and pressed, rolling compositing is carried out at the high temperature, and the titanium / aluminum / magnesium composite plate finished product is obtained. The titanium / aluminum tooth-shaped face composite rolling, magnesium alloy tooth-shaped face rolling and titanium / aluminum / magnesium composite rolling after tooth-shaped face engaging can be carried out under the different temperatures, and rolling composite is achieved; after tooth-shaped composite face engaging, rolling is carried out, synchronous engaging of multiple layers of alloy boards can be facilitated, the composite contact area can be effectively increased, composite face high-temperature oxidization is prevented, the stress state of the composite board interface can be changed, and the advantages that the composite board interface isgood in quality, and strength is high are achieved.

Description

technical field [0001] The invention relates to a rolling preparation method of a tooth-shaped joint surface of a titanium / aluminum / magnesium composite plate, which belongs to the field of metal composite plate preparation. Background technique [0002] Magnesium and magnesium alloys are currently the lightest metal structural materials in engineering applications. Due to their high specific strength, high specific stiffness, excellent thermal and electrical conductivity, high damping and vibration reduction, and electromagnetic shielding, as well as excellent regenerative properties, they have become the next generation materials. The third largest metal engineering material after steel and aluminum alloy materials is an environmentally friendly and energy-saving structural material with development potential in the 21st century, showing broad application prospects in the automotive industry and aerospace. However, due to the poor room temperature plasticity and corrosion r...
