    摘要: A casting heat-resistance Mg alloy improved in heat resistance without relying upon expensive RE contains Cu. More specifically, it contains Al (8.0 weight %), Cu (1.0-5.0 weight %), Zn (2.0 weight %), Be (0.01 weight %) and Mg (the rest). The alloy can be prevented from deteriorating in corrosion resistance by adjusting the added amount of Cu to 1.0-1.5 weight %. The corrosion resistance of the alloy can be improved more by adding 0.5 to 1.0 weight % Mn as well.

    摘要: The present invention provides a pressure casting method of a magnesium alloy. In the method, a molten magnesium alloy is cooled to form a partially molten state containing a solid-phase, and the partially molten state is further cooled to form a solid-phase granularly crystallized solid material. The solid material is partially-melted and pressure cast into a mold by a molding machine. A ratio of primary crystals in said solid material is set to 55 to 65%. The solid material is partially-melted in a solid-phase and liquid-phase coexisting state at a selected heating temperature so that a semi-solid having thixotropic properties and having the size of a main solid phase of 50 to 250 μm and a solid-phase ratio of 30 to 70% is formed. The semi-solid is pressure cast into a mold through a nozzle while maintaining the semi-solid state to form metal products having a ratio of primary crystals of 20 to 50%.

    摘要: The present invention provides a method for manufacturing a composite of a carbon nanomaterial and a metallic material which has a homogeneous composite metal structure and thixotropic properties by compositing a metallic material of a non-ferrous metal alloy with a carbon nanomaterial by using both stirring and ultrasonic vibration. The method comprises compositing the metallic material of the non-ferrous metal alloy with the carbon nanomaterial by adding the carbon nanomaterial in a state where the metallic material shows thixotropic properties by spheroidization of solid phase in a semi-solid state, and the compositing is performed by a process for stirring and kneading the semi-solid metallic material while keeping the temperature thereof at a solid-liquid coexisting temperature, and a process for dispersing the carbon nanomaterial to liquid phase between solid phases by ultrasonic vibration.
