Abstract: A method for producing an aluminum wire that has high strength and high conductivity even when reduced in diameter while having excellent elongation and improved in productivity. A method for producing an aluminum wire includes a solution step of subjecting a heat-treatable aluminum alloy material to a solution treatment, a wire-drawing step of subjecting the solution-treated aluminum alloy material to wire-drawing processing, a softening step of subjecting the wire-drawing processed aluminum alloy material to a softening treatment in a short time within 10 seconds, and an aging step of subjecting the softening-treated aluminum alloy material to an aging treatment.
Abstract: This hot work tool steel has a composition containing C: 0.45 to 0.57 mass %, Si: 0.05 to 0.30 mass %, Mn: 0.45 to 1.00 mass %, Cr: 4.5 to 5.2 mass %, Ni: 0.5 mass % or less, Mo+(½) W: 1.0 to 2.0 mass %, V: 0.30 to 0.80 mass %, and N: 0.008 to 0.025 mass %, the remainder being Fe and unavoidable impurities, and the area ratio of carbide having an equivalent circle diameter of 1 ?m or less being 20% or higher. It is thereby possible to improve thermal conductivity to thereby shorten cycle time, and improving hardness after heat treatment to improve abrasion resistance while sufficient hardenability is maintained. Consequently, it is possible to obtain a hot work tool steel having excellent toughness with high hardness, excellent corrosion resistance, and minimal degradation of machinability.
Abstract: A system for recovering precious metals includes a rotatable drum, recyclable materials, and a separating solution. The rotatable drum is configured to receive recyclable materials. The recyclable materials include non-metallic materials and electronic components, with one or both of the non-metallic materials and the electronic components having attached thereto one or both of base metals and precious metals. The separating solution is disposed in the rotatable drum and is configured to separate the base metals and the precious metals from the electronic components and the non-metallic materials and to separate the electronic components from the non-metallic materials. The rotatable drum is configured to agitate the recyclable materials and to wash the recyclable materials with the separating solution. The electronic components, non-metallic materials, base metals, and precious metals are each separately removable from the separating solution.
Abstract: The invention provides magnesium alloys for high temperature applications that combine excellent castability with superior corrosion resistance, and with good creep resistance, ductility, impact strength, and thermal conductivity. The alloys contain mainly Al, La, Ce, and Mn, and are particularly useful for high-pressure die casting process.
