Description
Technical field
The present invention relates to a kind of aluminum alloy materials and making method, belong to metal material field.
Background technology
Aluminium is pure white light metal, has ductility, and commodity often make bar-shaped, sheet, foil-like, powdery, band shape and thread.The oxide film that one deck prevents metallic corrosion can be formed in damp atmosphere.Aluminium powder and aluminium foil heat fierce burning in atmosphere, and send dazzling white flame.Be soluble in dilute sulphuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, be insoluble in water.The content of aluminium in the earth's crust is only second to oxygen and silicon, and occupying the 3rd, is the metallic element that in the earth's crust, content is the abundantest.The development of aviation, building, the large important industry of automobile three, requires that material behavior has the peculiar property of Aluminum-aluminum alloy, and this is just conducive to production and the application of this new metallic aluminium greatly, and the application of aluminium is very extensive.
Aluminium alloy is a most widely used class non-ferrous metal structured material in industry, widely apply in Aeronautics and Astronautics, automobile, machinofacture, boats and ships and chemical industry, the develop rapidly of industrial economy, increasing to the demand of Welded structural part, the Research on Weldability of aluminium alloy is also stretched into thereupon.Aluminium alloy density is low, but strength ratio is higher, and close to even exceeding high-quality steel, plasticity is good, can be processed into various section bar, has excellent electroconductibility, thermal conductivity and corrosion stability, and industrial wide use, usage quantity is only second to steel.Some aluminium alloys can adopt thermal treatment to obtain good mechanical property, physicals and corrosion resistance.The widespread use of aluminium alloy facilitates the development of aluminum alloy solder technology, and the Application Areas of aluminium alloy has been expanded again in the development of welding technique simultaneously, therefore, and welding technique just one of focus becoming research of aluminium alloy.
Aluminum alloy materials applies to building, civilian and industrial circle in a large number, and the requirement that current industrial high-strength aluminum alloy material is much different, as, require that there is high strength, high tenacity and good machine-shaping property, highly corrosion resistant ability, have kinds of surface handling property or good heat treatment performance etc.At present, the quantity that high strength alumin ium alloy uses at industrial circle and increasing extent large, but existing high-strength aluminum alloy material can not meet the requirement of industrial circle far away.Existing high-strength aluminum alloy material only meets above-mentioned partial condition, can not meet above-mentioned all conditions simultaneously, especially can not meet at aspect of performances such as machine-shaping, surface quality, thermal treatments.This also makes the use of high-strength aluminum alloy material in industrial circle receive restriction, affects the usage quantity of aldural at industrial circle.To sum up, the aluminum alloy materials general requirement applying to industrial circle has high strength, high tenacity, great surface quality and kinds of surface processing power, but because this aluminium alloying degree is high, there is machine-shaping difficulty in it, heat treatment requirements is high, surface quality is poor, the deficiency of the painstaking difficulty in surface.
It is high that high strength alumin ium alloy has intensity, plasticity is good, the features such as the good and fine corrosion resistance of weldability, being widely used on the various structural part of aircraft and the high heavily stressed welding structural element of other requirement of strength, is indispensable important feature material in current many dual-use aircrafts, transport facility.Along with space flight and aviation technical development is to the raising day by day of material requirements, it is higher that researchist is just putting forth effort mining inetesity, the high-strength weldable aluminium alloy of high comprehensive performance, at present for improving the over-all properties of the aldural of welding, mainly while pursuit material high strength, reduce, because intensity improves, detrimentally affect is caused to anti-stress corrosion performance, fracture toughness property and fatigue strength etc.
Along with the requirement of every profession and trade to aldural improves day by day, and propose high-load, lighting, high-strength, a series of requirement such as high-ductility, high-modulus, good corrosion resistance and welding property, but current research is in the welding property pursuing high strength simply, high toughness Al-alloy ignores raising material, make existing aluminum alloy materials or intensity high and welding property difference or good welding performance courage intensity low, to cause in the size Selection of part aluminium alloy structure part deflection with size the thicker and good material of welding property.Accessory size is thicker in two fermentation reasons: the intensity not reaching needs on the one hand because intensity is low, therefore solves required high-load problem by thickness; Existing aluminium alloy great majority pursue high-intensity high-tenacity on the other hand, and on intensity basis, seldom to pay attention to welding property, therefore, deficiency in height hides Welded, make the structural part of aluminium alloy can be partial to intensity in the choice low and have the material of good welding property, thus the accessory size that can cause is thicker causes the requirement that cannot meet aluminum alloy junction component high-load and lighting.
Contriver retrieves discovery, and application number is the patent of invention (a kind of ferroalloy materials) of 201210225837.7, it is characterized in that: the metallic element of component alloy material is Fe, Co, Ni, Cu, Cr; Alloy material each element percent mass composition: Co 16.81 ~ 17.08, Ni16.83 ~ 17.20, Cu 17.69 ~ 18.40, Cr 14.58 ~ 15.37, Fe 32.02 ~ 33.05, all the other are impurity element, and the mass percent sum of each component is 100%.Its advantage is: ferroalloy materials provided by the invention, adding each element makes alloy material have good strength, toughness and mechanical property, thus there is good compressive strength and plasticity, with the rising of thermal treatment temp, this Material compression intensity does not significantly reduce, and plasticity is significantly promoted, alloy material has high thermal resistance simultaneously.Alloy material annealed insulation after 5 hours at 800 DEG C of temperature, the intensity of alloy material and plasticity over-all properties the best.But this ferroalloy materials production process is complicated, and cost of manufacture is high, and the cycle is long.
Also retrieval finds that application number is a kind of silver alloy of disclosure of the invention and its preparation technology of 201310712907.6, silver alloy is made up of the alloying constituent of components by weight percent: silver-colored 85-96, copper 1-3, zinc 1.0-1.6, palladium 0.2-1.0, cadmium 0.2-0.8, zirconium 1.2-2.0, ruthenium 1.1-2.0, magnesium 0.5-1.3.This invention improves the resistance to elevated temperatures of silver alloys, ductility and hardness, silver alloy is made to be easier to moulding, and add in silver alloy reticulated structure, improve the resistance to overturning of silver alloy and the ductility of silver alloy, silver alloys is made to be easier to machine-shaping, because cancellated ternary alloy wire is more careful, and be wrapped in the binary alloy of silver-copper, do not affect the aesthetics of the quality of silver alloy and the ornaments after processing.Plasma cleaner cleaning can make silver alloy not oxidizable.But the material cost of this patent is high, because higher price causes range of application limited, can not widespread use.
