摘要： PURPOSE:To produce an Al-base composite billet for extrusion working in a high yield of raw materials by packing a specific material into the rear end or further front end part of a cylindrical molding chamber at the time of sintering a powder mixture composed of an Al metal and ceramics in the molding chamber. CONSTITUTION:The mixture 1 composed of the powder of Al or Al alloy and powder of the ceramics such as SiC, Si3N4 or Al2O3 as a reinforcing material is packed into a capsule made of a soft metal for hot isostatic pressurization. Powder of the Al alloy having the solidus line temp. higher than the solidus line temp. of the above- mentioned Al or Al alloy is packed into the rear end part 2 or further the front end part 3 of the capsule. The capsule is then hermetically sealed by deaerating the inside of the capsule. The capsule is pressurized and heated by the hot isostatic pressurizing treatment to sinter the mixture composed of the Al alloy powder and the ceramic powder. The composite material of the Al and ceramics is produced by extrusion working of such sintered billet. Parts 5 at the front and rear ends without contg. the costly ceramics are cut, by which the composite extrusion molding of the Al and the ceramics is produced in high yield of the raw materials.
