Abstract
PURPOSE:To economically produce an anisotropic permanent magnet having excellent magnetic characteristics by packing powder of an Mn-Al-C alloy into a thin container having plasticity and subjecting the powder to cold isotostatic compressing, then to warn plastic working at a specific temp. CONSTITUTION:The powder of the Mn-Al-C alloy produced by an atomization method, etc., is packed into the thin container having plasticity. The material for said container is preferably a carbonaceous stock such as carbon sheet. The alloy powder is then molded together with the container by the cold isostatic compression. The alloy powder is thereby solidified to a good shape and the molding having sufficient handling strength is obtd. This molding is subjected to the warm plastic working by extrusion working, rolling, etc., in a 530-780 deg.C range. The alloy essentially composed of a face-centered tetragonal crystal is thereby plastically deformed to form the agglomerate having the acicular shape in which the major axis direction is arranged in a specific direction or the disk shape in which the planes are arranged in parallel with each other. This agglomerate, therefore, forms the anisotropic permanent magnet which is secure and has the excellent magnetic characteristics.
