摘要： PROBLEM TO BE SOLVED: To produce a high strength Al alloy easy of porthole extrusion by regulating the hardness of a high strength Al alloy to specific Vickers hardness by annealing treatment before extrusion and further regulating its hardness to specific Vickers hardness by plastic working. SOLUTION: At the time of extruding a high strength Al alloy, an Al alloy ingot before extrusion is heated and held at about 440-550 deg.C and cooled to remove internal stress and homogenize the ingot, by which a Vickers hardness of >=Hv40 is provided. Subsequently, plastic working is applied to the homogenized Al alloy ingot at =40% working rate to develop work hardening, by which a Vickers hardness of >=Hv20 is provided. By this method, the high strength Al alloy easy of porthole extrusion can be obtained.

摘要： PURPOSE:To eliminate deformation in recesses and projections on the surface of a disc part by complexly reinforcing a part which defines a cooling hole in the disc part with reinforcing material, and making a region which is not complexly reinforced with reinforcing material to be included in a part which faces to the rib part of the disc part. CONSTITUTION:The main body of rotor 12 is made of A1 alloy. A part which defines a cooling hole 26 in disc parts 18 and 20 is complexly reinforced by a reinforcing material 28 over the whole length. The part which faces to rib part in the disc parts 18 and 20 is reinforced by the reinforcing material 28 only on its surface, and it is made of A1 alloy only in other regions. A wear- resistant covering layer 29 is formed on the circular plate-like surface of the disc parts 18 and 20. Thus, it is possible to eliminate deformation in recesses and projections on the surface of disc parts.
