摘要： PURPOSE: To obtain a superhigh tensile steel with superior toughness and strength, by especially reducing the content of C and by adding prescribed percentages of Ni, Mo, Ti, Al and Cu.
CONSTITUTION: This high tensile steel consists of, by weight, ≤0.05% C, 10W 25% Ni, 0.2W4.0% Mo, 0.1W5.0% Ti, 0.01W3.0% Al, 0.01W6.0% Cu and the balance essentially Fe. The steel is provided with high strength and toughness like 18% Ni maraging steel by utilizing hardening by the precipitation of an intermetallic compound. A martensite matrix phase with superior toughness is formed by adding 10W25% Ni, and Ti, Al and Cu are added as precipitation hardening elements. An intermetallic compound is precipitated in the matrix phase by aging to harden the steel. To ensure toughness at a superhigh strength level, the C content is restricted to a minimum, and the amounts of P and S as impurities are reduced to the utmost.

摘要： PURPOSE:To efficiently remove a reinforcing material, e.g. from the scrap of an Al composite material and to produce a high grade Al by subjecting the Al composite material, reinforced by specific percentages of reinforcing material, to melting under specific temp. conditions and then to filtration through a filter. CONSTITUTION:An Al composite material and an Al-based alloy composite material, reinforced by a reinforcing material (ceramics whisker, etc.) in 5-35% volume ratio, are melted at a temp. in the range between the liquidus temp. of matrix and 900 deg.C and filtered through a filter (glass filter, etc.). By this method, only the reinforcing material is formed into hanging state and the molten Al and the molten Al-base alloy alone are filtered, and as a result, high grade Al and Al-base alloy can be recovered from the scrap and waste materials of the Al composite and the Al-base alloy composite.

摘要： PURPOSE:To produce a homogeneous Al or Al alloy composite material free from internal defects such as pares and voids, furthermore free from the generation of the volatile loss of alloy elements even in the case high volatility alloy elements are added and the regulation of the components is executed and showing stable physical properties of high levels even in any of heat resistance, specific strength, specific elasticity or the like. CONSTITUTION:The molten metal of Al or an Al alloy is added with carbide forming elements and a solid carbon source. While being stirred, the molten metal is brought into reaction at 1100 to 1500 deg.C to form and disperse carbide grains. After the temp. of the molten metal is reduced to the liq. phase temp. to below 1000 deg.C, casting is executed, or after the reduction of the temp., high volatility alloy elements are added thereto to regulate the components, and casting is executed.
