Description
Technical field
The invention belongs to aluminium alloy manufacturing technology field, being specifically related to a kind of mixture with aluminum oxide, titanium compound, zirconium dioxide, scandium oxide is raw material, adopts the fused salt electrolysis eutectrol process to make the manufacture method of the multicomponent microalloying aluminium alloy of titaniferous, zirconium, scandium.
Background technology
Ultra-high-strength aluminum alloy has very high intensity and toughness, is the high-strength light structured material that aerospace field has application prospect.Usually add multiple alloying elements such as titanium, zirconium, scandium in the ultra-high-strength aluminum alloy and carry out combined microalloying, improve its every performance.Titanium elements forms many intermetallic compound TiAl in aluminium alloy
3Particle provides large quantities of heterogeneous body forming core bases, promotes the a-Al nucleation, thereby makes the as-cast structure refinement.Zirconium can improve the aluminium alloy recrystallization temperature, improves the stability of sosoloid, and improves aluminium alloy welding performance, improves the anti-stress corrosion performance of some aluminium alloy.Compare with zirconium, micro-scandium joins in the aluminium alloy, can significantly improve intensity, plasticity, welding property, high-temperature behavior, the etch resistant properties of alloy.But prices are rather stiff for scandium, limited its application to a certain extent.The scandium of trace and the compound interpolation of zirconium have significantly recrystallize restraining effect and grain refining effect to aluminium alloy.This is because zirconium can effectively promote disperse, tiny secondary Al in alloy

Usually add aluminium titanium master alloy in the aluminium alloy and carry out the interpolation of titanium elements.Aluminium titanium master alloy by aluminium and fluorine-containing hydrochlorate (as potassium fluotitanate K
2TiF
6) reaction prepare, environmental pollution is serious; Or adopt mixing the method preparation by fine aluminium and pure titanium, this can consume the insufficient pure metallic titanium of a large amount of China production capacity.
At present, industrially mainly contain two kinds of aluminium alloys and add the zirconium method: compound method, intermediate alloy process.The compound method is for directly directly adding K in being not less than 800 ℃ aluminium alloy melt
2ZrF
6, this method zirconium casting yield height, but smelting temperature height, energy consumption is big, and melt oxidation, air-breathing, slag inclusion significantly increase.Master alloy adds zirconium and is meant that mainly aluminium zirconium hardener adds zirconium, and the advantage of this method is that adding technology is simple, but the casting yield of zirconium is low, and it is higher to add the zirconium cost, and ZrAl
3Be easy to generate decay.
Scandium in the aluminium alloy is mainly added by the mode of scandium bearing master alloy.Scandium bearing master alloy is usually by following three kinds of methods preparation: with the metal scandium is raw material, adopts mixing the method preparation, and the burn out rate of scandium is big, the cost height; Scandium fluoride, Scium trioxide thermit reduction complex process, cost is higher; The advantage of Scium trichloride melt hot reducing method is that reduction temperature is low, can carry out in common resistance furnace, and shortcoming is that the Scium trichloride water-absorbent is strong, can produce thoroughly reductive oxychlorination scandium.
