摘要： The invention provides a method for injection molding a semi-molten melt of metal to a product, wherein a semi-molten melt of metal is injected into a cavity of the mold through a nozzle of injector to mold the product which is divided in a lower solid fraction portion to require strength and a higher solid fraction portion to require molding accuracy along flow of the melt inside the cavity. In the method of the invention, a part of the melt to be earlier injected is determined to be at a lower temperature in the injector than a part to be later injected among the melt parts composing said lower and higher solid portions in the cavity by injecting a batch of the melt, and that the melt is injected into the cavity on the side on which said lower solid fraction portion for the strength of the product is formed.

摘要： Material characteristics that a foamed filler material (s) to be filled in a frame cross section (fr) should have are discussed. By using a material complying with the characteristics, the energy absorbability of the frame (fr) is effectively enhanced. In a frame structure (fr) for vehicle bodies in which a filler material is filled in at least part of the cross section of a frame, the filler material is set to a mean compressive strength of not less than 4 MPa and/or a maximum bending strength of not less than 10 MPa. More particularly, the filler material is set to a mean compressive strength of not less than 5 MPa and/or a maximum bending strength of 60 MPa.

摘要： A method is provided for producing a preform structure which is used in a composite aluminium or aluminium alloy component in which a base metal of an aluminium or aluminium alloy is reinforced with reinforcing materials. A slurry is prepared by mixing reinforcing materials including ceramic particles and first whiskers with burning-away powders and liquid. Liquid components contained in the slurry are filtered to provide a dehydrated structure. Thereafter a preform structure is produced by sintering the ceramic particles with the first whiskers after burning the burning-away powders in the dehydrated structure.

摘要： In a semi-solid alloy including a large amount of a liquid phase portion, that is, semi-solid alloy with less than 50% of solid phase rate, there is a tendency for a solid phase portion to concentrate into the central portion in the direction of thickness, that is the internal portion. In order to enhance corrosion resistance at a portion where high corrosion resistance is particularly required in parts molded by semi-solid injection, the above tendency is utilized. By utilizing the tendency, a layer consisting of a liquid phase portion is partially formed at the semi-solid state on a surface portion where high corrosion resistance is required.
