The present disclosure provides a magnesium alloy and a preparation method and an application thereof. Based on the total weight of the magnesium alloy, the magnesium alloy includes 0.8-1.4 wt % of rare earth element, 0.01-0.2 wt % of R, 0.8-1.5 wt % of Mn, 0-0.01 wt % of Fe, 0-0.01 wt % of Cu, 0-0.01 wt % of Ni, 0-0.01 wt % of Co, 0-0.01 wt % of Sn, 0-0.01 wt % of Ca, and 96.84-98.39 wt % of Mg, wherein R is at least one selected from Al and Zn.

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 contain 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.

A method of making a light weight component is provided. The method including the steps of: forming a metallic foam core into a desired configuration; applying an external metallic shell to an exterior surface of the metallic foam core after it has been formed into the desired configuration; forming an inlet opening and an outlet opening in the external metallic shell in order to provide a fluid path through the metallic foam core; and injecting a thermoplastic material into the metallic foam core via the inlet opening.

Processes for forming blanks having tailored properties in localized areas are provided. The blanks are then formed into three-dimensionally shaped components (e.g., high-strength automotive parts). A sheet of high-strength metal alloy may be selectively heated in a first region to a temperature below a melting point of the metal alloy with a heat source, while a second region of the sheet adjacent to the first region remains unheated. The selective heating creates a first region of the metal alloy having at least one material property distinct from the second region. After the sheet is cut to form a blank, the blank comprises a portion of the first region and a portion of the second region. In this manner, a plurality of distinct tailored regions may be formed on each blank. The process may be continuous or semi-continuous and further include cutting of blanks from the sheet. High-strength structural components are also provided.
