Preferably, described pouring temperature is 730 ℃.
Preferably, described coverture is CaF 2+ MgCl 2+ CaCl 2Or CaF 2+ MgCl 2+ MgF 2
In to the aluminium alloy capability Study of Lifting, find that scandium (Sc) is that the most effective up to now alloy adds element, it belongs to the 3D transition elements, the rare earth element that is centered on by the 4f electronics with skin has tangible performance difference, its lattice paprmeter, density and some physics, mechanical property more approaches aluminium, yttrium and titanium, it is the desirable alloy element of aluminium alloy, aluminium there is good dispersion-strengthened action, be the most strong grain refiner of aluminium alloy and effective crystallization inhibitor again, the structure of alloy and performance are produced significantly influence, and the adding of an amount of scandium makes the intensity of aluminium alloy, hardness, welding performance, decay resistances etc. are greatly improved.Its strengthening mechanism is: except that a small amount of solid solution, major part is with Al in aluminium alloy for scandium 3The Sc particle form is separated out, i.e. the nascent Al of casting 3The secondary Al of Sc and hot-working 3Sc, the nascent Al of casting 3Sc has identical lattice types and extremely low coherence mismatch with aluminum substrate, becomes effective heterogeneous body nucleus, and refinement alloy casting state grain structure improves alloy strength, the secondary Al of hot-working 3The Sc particle further improves intensity and suppresses alloy recrystallization by the formation of pinning dislocation and obstruction sub boundary, makes alloy all can keep stable non-recrystallized structure in hot-working or annealing in process state, thereby keeps its good toughness and tenacity.
In containing scandium-aluminum alloy, add other transition element Mn, Zr etc., the beneficial effect when the compound interpolation of scandium and these elements has not only kept adding scandium separately, and can improve the particle heat endurance, the Zr that adds trace can make Al 3The Sc facies evolution forms ternary Al 3(Sc, Zr) compound particle further reduce the mismatch with aluminum substrate, and the beneficial effect of Sc is improved.
Al-Mg is that alloy and Al-Zn-Mg are that alloy generally all adopts high magnesium Al-Mg serial alloy welding wire welding (magnesium (Mg) content 〉=3% o'clock is called high-magnesium aluminum alloy generally speaking), when content of magnesium increases, add other and add element, the viscosity of aluminium alloy melt increases during melting, the mobile reduction makes troubles can for like this casting and following process.In aluminium alloy, add the flowability that an amount of cerium (Ce) and lanthanum (La) can improve alloy, reduce the influence that high magnesium alloy viscosity produces alloy greatly, can reduce the consumption of Sc on the other hand, not only reduced cost but also produce compound action with Sc, further crystal grain thinning, improve the extension limit and the heat endurance of alloy, simultaneously can also with the Al in the aluminum melt 2O 3[H] reacts, and plays the effect that purifies melt.
Using Sc of the present invention, Zr multi-element composite micro-alloying Al-Mg-Sc serial alloy welding wire molten solder Al-Zn-Mg (Sc) is that alloy and Al-Mg (Sc) are alloy, and the weld seam alloy has obtained the tissue of tiny homogeneous, and the welding point hot cracking tendency obviously descends; Add 0.2%~0.4% lanthanum (La) and cerium (Ce) in the alloy welding wire and improved the flowability of alloy melt, weakened high magnesium alloy fused mass viscosity and be difficult to the influence of moulding greatly the ingot casting cast, simultaneously under welding temperature, also has good mobility as welding wire, preferentially selecting cerium in the mixture of cerium and lanthanum for use is 60%~80%, lanthanum is 40%~20%, the more satisfactory while of the mobile performance of welding wire can better be played the effect that purifies melt like this, ratio when the content of the content of manganese (Mn) and scandium (Sc) in the aluminium-magnesium-scandium alloy is 1.5~1.8: in the time of 1, alloy has excellent corrosion resistance, therefore alloy welding wire of the present invention has higher flowability under welding temperature, can obtain excellent more seam organization, reduce weld seam alloy welding hot cracking tendency, postwelding obtains higher strength of joint, and has stronger corrosion resistance.
