specific Embodiment approach 3

[0017] Manufacture a piece of aluminum alloy-titanium composite material, which can also be applied to aluminum alloy plates. The grade of the base titanium plate is TA2, the size is 6×1500×2800mm, the double layer is aluminum alloy 5083, the size is 8×1500×2800mm, the double layer The support height between the aluminum alloy plate and the base titanium plate is 7mm, and the surface of the steel backing plate is paved with a buffer protection layer. Ammonium ladder explosives are used and placed directly on the surface of the aluminum layer. The charge per unit area at the detonating end is 3.00g / cm 2 , the amount of charge per unit area within the range of 700mm at the end of the detonation direction is gradually reduced to 1.6g / cm 2 , detonated with an industrial electric detonator, and the aluminum alloy-titanium composite material obtained by explosive welding has good composite quality and good shape. Tensile strength ≥ 100Mpa, explosive composite rate 100%.

Abstract

The invention discloses an explosive welding manufacture method of an aluminium-titanium composite material, which is characterized in that a basic layer titanium plate (5) is arranged on a steel baseplate (7) where a damping protection layer (6) is paved; a composite layer aluminium (aluminium alloy) plate (3) is arranged on the basic layer titanium plate by a supporting part (4); explosive (2) is arranged on the surface of the aluminium (aluminium alloy); non-uniform explosive arranging type is adopted at the end in the explosion direction, which leads explosive quantity per unit area is gradually reduced at the end in the explosion direction; therefore, large-area aluminium (aluminium alloy)-titanium composite material is obtained through explosion welding and composition into a whole; wherein, the material of a basic plate is industrial pure titanium; the material of a composite plate is pure aluminium or aluminium alloy (the content of Mg is not more than 0.1%). The aluminium (aluminium alloy)-titanium composite material made by using the method has good quality.

Description

Technical field: [0001] The invention relates to the technical field of manufacturing metal composite materials, in particular to an explosive welding manufacturing method of aluminum-titanium composite materials. Background technique: [0002] Explosive welding is a metal processing method that uses explosives as the energy source, and under the action of the explosive explosion load, the clad metal collides with the base metal at high speed and is firmly connected together. Aluminum (aluminum alloy)-titanium composite materials have broad application and development prospects in the fields of aviation industry, cooker industry, chemical industry, naval vessels, and special solder. However, due to the low impact toughness of the titanium plate against explosive loads, during explosive welding, especially when the thickness of the titanium plate is thinner, the thickness of the aluminum (aluminum alloy) is thicker, and the surface area of ​​the plate is large, there will be ...
