Abstract
PURPOSE: To obtain a structure contg. fine carbide dispersed unifomly in the martensitic iron alloy matrix by molding and heat treating alloy powder obtd. by reducing a mixture of metallic oxide powder with carbon powder.
CONSTITUTION: Metallic oxide powder having an alloy composition is mixed with carbon powder required to reduce the metallic oxide, and themixture is pulverized to ≤1μm average grain size. This pulverized material is reduced with heating in an H2 atmosphere to form alloy powder. After regulating the composition and grain size of the alloy powder, the powder is molded and sintered in a vacuum. This sintered body is isotropically compressed in an inert gas atmosphere and heat treated. Thus, a structure contg. fine carbide dispersed uniformly in the martensitic iron allloy matrix is obtd.
