Abstract
PURPOSE: To obtain the desired shape and size and high magnetic characteristics by molding Mn-Bi alloy powder obtd. by rapid cooling after melting, coating the surface of the molding with a protective film, and sintering the coated molding at a specified temp.
CONSTITUTION: Mn-Bi alloy powder obtd. by rapid cooling after melting is molded, and a protective film of Al, Cu, Ni or the like which is hardly reactive with the Mn-Bi alloy is formed on the surface of the molding by an ordinary method. The molding having the surface protective film is then sintered at 250W360°C. It is desirable to apply a magnetic field having ≥1KOe intensity in the sintering.
