Embodiment 1

[0033] A preparation for a 1.5mm layered titanium / aluminum composite plate, comprising the steps of:

[0034] (1) Select annealed soft TAl and 2024 plates as explosive blanks. The specifications of the TAl plate are length 850mm×width 850mm×thickness 1mm, and the specifications of 2024 plate are length 800mm×width 800mm×thickness 4mm;

[0035] (2) Grind and clean the surface of the TAl and 2024 plates to be combined by mechanical grinding; if the TAl plate is warped during the grinding process, it must be leveled before explosive welding;

[0036] (3) Assemble the TAl and 2024 plates that have been polished to be composited, the TAl layer is on the upper 2024 layer, and the prepared explosives are tiled on the upper surface of the TAl plate for explosive welding. The main explosive welding process parameters are; Using ammonium oil mixed explosives, its composition (weight ratio): NH 4 NO 3 content of 50-90%, diesel oil content of 1-15%, sawdust content of 1-15%; explosive d...

Abstract

The invention relates to a laminated titanium aluminum clad plate and a preparation method thereof. The laminated titanium aluminum clad plate is characterized in that the titanium aluminum clad plate consists of an aluminum alloy substrate layer and a titanium-coated layer; and the total thickness is 1.5 mm. Compared with a TAI plate material with thickness of 1.5 mm, the laminated titanium aluminum clad plate can save a titanium material by 80 percent around so as to reduce the material cost and also reduce the whole density of the plate material by about 35 percent; and compared with a 2024 plate material with the thickness of 1.5 mm, the laminated titanium aluminum clad plate not only improves anticorrosive performance and thermal shock resistance of the material but also improves the whole mechanical performance of the plate material.

Description

Technical field [0001] The invention relates to a layered titanium-aluminum composite plate and a preparation method thereof, in particular to a layered titanium-aluminum composite plate thin plate with a thickness of 1.5mm, and the preparation of a 1.5mm-thick layered titanium-aluminum composite plate through the combined application of explosion welding and rolling processes. Titanium-aluminum composite plate and preparation method thereof. Background technique [0002] As a structural material, titanium has many excellent properties, such as low density, high specific strength, corrosion resistance, high temperature impact resistance, etc., but the price of titanium is relatively high. Although aluminum has low price, low density, and good thermal conductivity, it is corrosion-resistant and The high temperature impact resistance is poor. Layered titanium-aluminum composite panels not only have a lower density than titanium, but also combine the excellent thermal conducti...
