    摘要： The present application discloses a low-pressure casting secondary pressure process for an aluminum wheel. The characteristics of smooth low-pressure filling of molten aluminum alloy and rapid solidification of a rim are preserved, the aluminum alloy at a center sprue is frozen by using a center sprue spreader and a forced water coolling to close a mold cavity, and secondary pressure is implemented to the aluminum wheel by means of down-movement of center extrusion rods, so that the material mechanical properties of an aluminum wheel casting and the production efficiency of the casting process are improved.

    摘要： A castable, moldable, or extrudable structure using a metallic base metal or base metal alloy. One or more insoluble additives are added to the metallic base metal or base metal alloy so that the grain boundaries of the castable, moldable, or extrudable structure includes a composition and morphology to achieve a specific galvanic corrosion rates partially or throughout the structure or along the grain boundaries of the structure. The insoluble additives can be used to enhance the mechanical properties of the structure, such as ductility and/or tensile strength. The insoluble particles generally have a submicron particle size. The final structure can be enhanced by heat treatment, as well as deformation processing such as extrusion, forging, or rolling, to further improve the strength of the final structure as compared to the non-enhanced structure.

    摘要： Provided are a method of molding an amorphous alloy, which has a high degree of work freedom regardless of components of an amorphous alloy, in particular, metallic glass and of the shape of an article to be molded, and is capable of producing a molded article having less pores, and a molded object produced by the molding method. The method of molding an amorphous alloy includes: a melting step of melting an amorphous alloy; a differential-pressure casting step of injecting a melt of the amorphous alloy into a casting mold positioned below the melt and evacuating the casting mold; and a processing step of processing the melt by heating and pressurizing the melt in the casting mold while keeping the melt in a supercooled state.

    摘要： An aluminum base part is composed of a forging cast product produced by a forging cast process and a nickel chromium plating layer formed on the forging cast product. The nickel chromium plating layer is composed of a semibright nickel plating layer formed on the forging cast product and having a thickness of 5 to 10 μm, a bright nickel plating layer 33 formed on the semibright nickel plating layer 31 and having a thickness of 5 to 10 μm, and a chromium plating layer 37 formed on the bright nickel plating layer 33 and having a thickness of 0.5 to 3 μm. The present invention adopts a forging cast product rather than a cast product. The forging cast product has a smooth surface, so that a plating layer can be directly formed on the surface of the forging cast product without forming an undercoat resin layer.
