摘要： The method of making a profiled work of aluminum or aluminum alloy comprises the steps of loading a billet of aluminum or aluminum alloy in a container having an extruding die at its one end and urging the billet against the extruding die by a ram so as to extrude the billet through the die to form a profiled work of aluminum or aluminum alloy with its cross-section conforming with that of the die. A disc of aluminum or aluminum base alloy containing at least one or two elements selected from the group consisting of elements B, Be, Ti, Zr, W, Mo and V is located between the extruding die and the billet before the billet is extruded. The element contained in the disc forms very hard and fine abrasive particles and the abrasive particles are extruded together with the mass of the billet through the extruding die so that the material of the billet sticking to the bearing surface of the extruding die is removed from the bearing surface and the bearing surface is polished so as to prevent the material of the billet from further sticking to the bearing surface thereby permitting the extruding velocity to be raised without causing any surface defects such as flaws, die-lines, pick-up and scores, while the brilliance of the surface of the extruded profiled work is raised and no local decolorization in the surface occurs after anodic oxidation treatment of the profiled work.

摘要： Sintered pieces of rapid-solidified aluminum alloy powder are friction stir welded together. The sintered piece may be composite material dispersing ceramic particle therein. A welding aid, which disperses the same ceramic particle as those in the sintered pieces, may be sandwiched between or mounted on the sintered pieces. A weld zone is formed without melting, so as to inhibit formation of blowholes or coarsening of metallographic structure. Consequently, the sintered pieces are welded together while retaining intrinsic properties of the sintered aluminum alloy.
