Abstract

The invention relates to an aluminum alloy material used for aerospace large heavy castings, and a preparation method of the material. The novel hypoeutectic aluminum alloy material with high strength and toughness is prepared from common aluminum in batches on the basis of aerospace standard ZL114A alloy through adjusting components of alloy, controlling the trace element content and adopting a batch production refining deterioration and melting preparation technology. The aluminum alloy material is suitable for aerospace large heavy castings and has same mechanical performances with performances of small-batch produced refined aluminum, the cost is reduced by 5000 yuan / t, and aerospace product batch production demands are met.

Description

technical field [0001] The invention belongs to the field of aluminum alloy manufacturing, and relates to an aluminum alloy material for large thick aerospace castings, in particular to an aluminum alloy material for large thick aerospace castings and a preparation method thereof. Background technique [0002] my country's aerospace products are mainly formed by the riveting structure of skin stringers, and the aluminum alloy materials are mainly deformed aluminum alloys with good strength and toughness. With the development of functional integration, more and more casting molding processes are adopted abroad, mainly because casting has the advantages of low cost, excellent comprehensive performance, strong reliability, and short manufacturing cycle. [0003] For example, the aerospace base is a large thick-walled part (thickness 0.2m, length 10m), which requires alloys with good fluidity and high mechanical properties. At present, ZL114A is mainly used in the aerospace fiel...
