Abstract
The invention relates to a laminated metal composite plate for an autobody. The laminated metal composite plate comprises two 5000 or 6000 series aluminium alloy plates and a titanium alloy foil sandwiched between the two 5000 or 6000 series aluminium alloy plates and the interfaces of the three plates are combined in a metallurgical bonding way. The preparation method of the laminated metal composite plate comprises the following steps: mechanically polishing 5000 or 6000 series aluminium alloy and a TC4 titanium alloy foil; arranging the TC4 titanium alloy foil between the two aluminium alloy plates to form a three-layer laminated plate; preheating in a resistance furnace; and rolling in a rolling mill. Since friction between the aluminium alloy plates and the surface of a roller causes a great deal of shear deformation and a strong shear texture is formed in the aluminium alloy plates due to property difference between titanium alloy and aluminium alloy, the forming property is remarkably improved. Moreover, a great deal of shear deformation induces grain refinement and the strength and plasticity of the aluminium alloy layers are improved. Small amount of TC4 titanium alloy foil is used, so that aluminium alloy is greatly enhanced, and the strength of extension of the laminated metal composite plate exceeds that of the same aluminium alloy plate by more than 30%.
Description
Technical field
The present invention relates to a kind of metallic composite panel and preparation method thereof.
Background technology
Continuing soaring and controlling the extremely urgent of greenhouse gas emission of fuel price, impels auto industry to update prior art and improves fuel economy and reduce exhaust emissions.The lightweight of automobile is the effective means realizing saving fuel oil and reducing exhaust emissions.Employing alloy in lightweight replacement ferrous materials is the main path of automobile lightweight.The advantages such as aluminium alloy has that proportion is little, specific strength is high, corrosion-resistant, recyclable recycling are the preferred material of automotive light weight technology, and current aluminium alloys for automobile is mainly be main with 6000 with 5000.But compared with automobile steel material, there is press formability shortcoming on the low side in aluminium alloy.The advantage such as TC4 titanium alloy has that proportion is little, intensity is high, wear-resisting, corrosion-resistant and shock resistance is good is light-weighted alternate material.But the restriction being subject to high cost is difficult to be widely used.
Summary of the invention
The object of the present invention is to provide one can meet automotive light weight technology requirement, intensity be high, good impact resistance, there is again layer metal composite plate material for body of a motor car of good formability and preparation method thereof.The present invention mainly with 5000,6000 line aluminium alloy sheet materials for matrix, adopt titanium alloy foil strengthen, by the metallic composite panel that hot rolling is standby.
Metallic composite panel of the present invention a kind ofly between two piece 5000 or 6000 line aluminium alloy sheet materials, accompanies titanium alloy foil and the layer metal composite plate material that combines of three pieces of sheet material metallurgical interfaces.
The preparation method of above-mentioned layer metal composite plate material is as follows:
(1) Material selec-tion: choose the TC4 titanium alloy foil that 5000 or 6000 line aluminium alloy sheet materials that the measure-alike thickness of length and width is 0.4 ~ 2.0mm and thickness are 0.1 ~ 0.3mm.
(2) polishing is clean: carry out mechanical grinding to aluminum alloy plate materials and TC4 titanium alloy foil surface, while removal oxide-film and dirt, increase roughness.
(3) method hot rolling: the TC4 titanium alloy foil after polishing a piece with the aluminum alloy plate materials that two pieces of trades mark after step (2) polishing are identical is clipped in the middle and forms three-layer metal lamination, then put into resistance furnace and carry out preheating, preheat temperature is 300 ~ 550 DEG C, time is 6 ~ 10min, then send into milling train to be immediately rolled, mill speed is 0.3 ~ 1.2m/s, and rolling reduction is 25 ~ 50%.
The present invention compared with prior art tool has the following advantages:
1, a large amount of detrusion caused by rubbing between aluminum alloy plate materials and roller surface and the difference of titanium/aluminium alloy capability cause forming strong shear texture in aluminum alloy plate materials, thus improve its formability; And grain refinement is brought out in a large amount of detrusion, improve intensity and the plasticity of aluminium alloy layer.
2, use a small amount of TC4 titanium alloy foil that aluminium alloy capability can be made to been significantly enhanced, the tensile strength of this layer metal composite plate material exceedes identical aluminum alloy plate materials more than 30%.
3, titanium alloy foil and aluminum alloy plate materials can compatible deformations, reduce aluminium sheet waste material.
4, the layer metal composite plate material interface cohesion of preparation is tight, without obvious hole and gap.
5, layer metal composite plate material of the present invention, while meeting lightweight requirements, also have good formability and high intensity, it has a good application prospect in the automotive industry.
