摘要： PROBLEM TO BE SOLVED: To inexpensively provide a differential gear case having sufficient rigidity, sufficient abrasion resistance, sufficient high-temperature strength and low thermal expansion properties. SOLUTION: An aluminum alloy has a composition comprising 12.0-14.0 mass% Si, 3.5-4.5 mass% Cu, 0.3-0.5 mass% Mg, 0.2-0.3 mass% Mn, 0.1-0.2 mass% Ti, 0.003-0.015 mass% P and the balance Al with unavoidable impurities. The method for manufacturing the differential gear case comprises the steps of: melting the above aluminum alloy; degasifying the molten metal until an amount of gas in the molten metal in a holding furnace becomes 0.1 cc/100 g of Al or less; then supplying the molten metal into a die at a casting temperature of 680 to 730°C; liquid-forging the molten metal with a molding pressure of 50 to 100 MPa; solution-treating the obtained liquid-forged product at 500 to 520°C; and then aging it at 160 to 190°C for 1 to 10 hours. Thus, heat-treated aluminum alloy has a structure in which primary Si crystals have the maximum particle diameter of 20 μm or smaller and eutectic Si crystals have the maximum length of 10 μm or shorter.

摘要： PROBLEM TO BE SOLVED: To provide a casting method into a metallic mold with which a magnesium alloy can be cast with a good burning resistance in the casting of this alloy into the metallic mold, and to provide a magnesium alloy cast product having high quality at a low cost. SOLUTION: This casting method into the metallic mold is the method, with which the mixture of at least one kind selected from a group composed of a high melting point metal, ceramics and graphite, and a surface active agent aqueous solution or a low boiling point liquid oil and fat, is applied to at least a part of the surface at a cavity side of the metallic mold, and a heating treatment is performed to form a coating layer stuck to the applied portion. Thereafter, the molten magnesium alloy is repeatedly cast into the metallic mold with the coating layer and before developing the burning after performing plural times of casting operations if desired, the mixture is again applied at least on a part of the surface at the cavity side of the metallic mold and heat treated to form the coating layer stuck to this applied portion. Thereafter, the molten magnesium alloy is repeatedly cast into the metallic mold with this coating layer.

摘要： PURPOSE:To collect the lubricant and to cool the head of a piston effectively, by forming a recessed portion to reach the rear side of a ring groove furnished at the outside of the head, at the lower side of the head against a cutting arranged at the pin hubs and the neighboring positions of the skirt. CONSTITUTION:The piston 1 for an engine consists of a head 2, a pair of pin hubs 3 arranged on the same axis at both sides of the piston axis Y projected unitary at the lower side of the head 2, and a skirt 4 connected unitary to the lower periphery of the head 2. In the skirt 4, a cutting 9 is formed at the neighboring positions of each pin hub 3 in the direction to the periphery. In such a composition, at the lower side of a ring belt 7 against the cutting 9, a recessed portion 12 is furnished, which is formed at least to reach the rear side of the third ring groove 83 which is engraved at the outside of the ring belt 7. Therefore, the lubricant collected to the cutting 9 is penetrated to the recession 12 to cool the head 2 effectively.
