Abstract

PURPOSE: To obtain easily sintered soft magnetic iron-silicon parts having excellent magnetic characteristics by maintaining a green compact or sintered body in a specific temp. range for specified time and solutionizing silicon into iron.
CONSTITUTION: The green compact or sintered body is maintained for the specified time at the temp. below the A3 transformation temp. and lower than about 910°C in the stage of mixing, compacting and sintering alloy powder consisting of iron and silicon and pure iron powder. The silicon is thereby thoroughly solutioned at the ratio corresponding to the concn. thereof in the α phase state and the metallic structure is made into the uniform structure in which the silicon is satisfactorily diffused. The sintered body is thereafter magnetically annealed. The sintered soft magnetic iron-silicon parts having the uniform structure, high density and excellent magnetic characteristics are obtd. by the above- mentioned.
