摘要： A castable, moldable, and/or extrudable structure using a metallic primary alloy. One or more additives are added to the metallic primary alloy so that in situ galvanically-active reinforcement particles are formed in the melt or on cooling from the melt. The composite contains an optimal composition and morphology to achieve a specific galvanic corrosion rate in the entire composite. The in situ formed galvanically-active particles can be used to enhance mechanical properties of the composite, such as ductility and/or tensile strength. The final casting can also be enhanced by heat treatment, as well as deformation processing such as extrusion, forging, or rolling, to further improve the strength of the final composite over the as-cast material.

摘要： An improved aluminum alloy for casting into a component, such as a vehicle component, is provided. The improved aluminum alloy includes at least 80 wt. % aluminum; 6.0 to 8.0 wt. % silicon; 1.0 to 2.0 wt. % zinc; 0.10 to 0.6 wt. % magnesium; 0.1 to 0.60 wt. % copper; 0.20. to 0.60 wt. % manganese; up to 0.25 wt. % iron; 0.015 wt. % to 0.03 wt. % strontium; and up to 0.15 wt. % titanium, based on the total weight of the improved aluminum alloy. This improved aluminum alloy can be formed by combining recycled aluminum or recycled aluminum alloy with at least one additional element. The cast component formed of the improved aluminum alloy has a yield strength of 120 MPa to 130 MPa and an elongation of 8% to 16%, depending on flow length, when the cast component is in the as-cast (F temper) condition.
