Title: Method for sintering metallic powder containing readily oxidizable element
Inventor: KUBO TOSHIHIKO
IPC: B22F3/10
Filed: 1986-02-06
Abstract: PURPOSE:To prevent oxidation ad decarburization during the sintering of a green compact of metallic powder contg. a readily oxidizable element by sticking an oxidation inhibitor to the necessary parts of the green compact and sintering the compact. CONSTITUTION:Fine powder of a metal, graphite or the like as an oxidation inhibitor is stuck to the necessary parts of a green compact of metallic powder contg. a readily oxidizable element such as low-alloy Mn-Cr steel powder. For example, the fine powder is kneaded with a solvent and the resulting paste is sprayed. The green compact is then sintered as usual. In this method, the penetration of H2O into the porous surface of the green compact is prevented and oxidation and decarburization during the sintering can be prevented. The lowering of the strength of the neck part can also be prevented.

Title: Method for heating billet of aluminum or aluminum alloy
Inventor: HISAMINATO SATOSHI
IPC: B21J1/06
Filed: 1994-01-27
Abstract: PURPOSE:To prevent the generation of defective products due to streaks by holding a billet for a specific time after raising the temperature, repeating the heating and the holding stepwise and thereby raising the temperature to the target. CONSTITUTION:A magnetic field is generated by causing a AC current to flow to the heating coil of an induction heater, an induction eddy current is generated in aluminum or aluminum alloy within the magnetic field, and thereby a base billet for extrusion is heated. In this case, after the temperature of the billet is raised lower than a target temperature for extrusion, the heating for the purpose of raising the temperature is suspended, the billet is held for a specific time, and the heating is resumed. This is repeated at least more than once, and the temperature of the billet is raised to the target while the heating and the holding are repeated stepwise to raise the temperature successively. Thus, improvement is attained in the mechanical characteristics and the yield of an extruded product.
