    摘要: A shaped material comprising powders of alloys containing easily oxidizable elements is fired in a hydrogen-based atmosphere containing at least one hydrocarbon gas in a total amount of 0.01-5.0 volume %. Therefore, the amount of oxides formed on the surfaces of material powder particles is reduced, and the sinterability of powder particle surfaces is improved owing to the sticking of atomic carbon thereto and thereby the mutual diffusion of powder particles becomes easy. As a result, there can be obtained a sintered alloy of desired density, superior in oxidation resistance, etc.

    摘要: A turbine rotor unit and a method of producing the same are disclosed. This turbine rotor unit comprises a ceramic rotor, a ceramic shaft integrally united with the ceramic rotor and a metal shaft provided with a cylindrical portion fixing the ceramic shaft therein and is characterized by having a gap between a substantial portion of the inner peripheral surface of the cylinder portion located near the side of the ceramic rotor and the outer surface of the ceramic shaft. Further, the turbine rotor unit is produced by arranging on one end of the metal shaft a cylindrical portion wherein an inner diameter at its opening side is larger than that at the bottom side, inserting the ceramic shaft into the cylindrical portion, and fixing the ceramic shaft to the cylindrical portion at its small diameter side.
