Abstract

Provided is a forming apparatus, which is enabled to form a compact having an extremely high orientation, by combining crystal break surfaces of alloy material powders having more equal crystal orientation relations in a magnetic field. The forming apparatus (1) comprises a cavity (22) to be charged with powders to be polarized in a magnetic field or an electric field, magnetic field or electric field generating means (4) for applying a magnetic field or an electric field to the powders having filled the cavity, agitating means (54) for agitating and orienting the powders having the magnetic field or the electric field applied thereto by the magnetic field or electric field generating means, and pressure means (31 and 32) for applying a compressing force to the powders agitated and oriented, thereby to shape the powders.
