The present invention prepares the aluminum alloy for automobile wheel hub using the technique of injection shaping, and injection shaping is to use high pressure inert
Alloy liquid stream is atomized into tiny molten drop by gas, is flown and is cooled down under high velocity air, and base is deposited into before not yet solidifying completely
A kind of technique of part.It, which has, obtains material structure fine uniform, can suppress the various of the flash set technologies such as gross segregation
Advantage, there is the advantage that one step is completed from alloy melting to near-net forming again, shaping will be sprayed applied to the hub for vehicle wheel
Preparation has advantages below：
1. low oxygen content：Because the time of deposition process is very short by (about 10-3S) and by inert gas shielding, deposition oxygen contain
Amount is far below the level of similar powder metallurgy, and similar to similar casting alloy.
2. the microscopic structure quickly solidified：Including forming tiny equiaxed grain structure (10~100 μm), gross segregation disappears
Remove, microscopic segregation and the generation of segregation phase receive suppressions, alloying component evenly with can form metastable supersaturation solid solution.
3. alloy property improves：Performance (such as anti-corrosion, wear-resisting, magnetic and intensity and the toughness physics and chemistry of spray formed material
Performance and mechanical property) it is greatly improved than conventional cast forging material, it is suitable with powdered metallurgical material.Alloy hot-working character is big
It is big to improve, make generally can not the founding materials of deformation processing can be with heat processing and forming, it might even be possible to obtain superplasticity.
4. technological process is short, cost is low：It is at present process route most short from melting to final products.Powder smelting can be avoided
The possibility that golden intermediate step pollutes, increase product reliability, there is stronger competitiveness than powder metallurgy product.
5. high efficiency：Single ingot blank quality is up to more than 1t and high yield rate, it is clear that is advantageous to industrialized production.
To obtain the hub for vehicle wheel of given size, preferable technical scheme is, in step B, using nitrogen to the alloy
Liquid carries out injection shaping, obtains a diameter of 100-500mm injection deposition blank.
