<p>Provided are a metallic material, e.g., an electromagnetic material (magnetic steel sheet), that has a processed surface along which crystal axes <001> of the metallic material have been distributed by controlling the distribution of the crystal axes <001>, and a process for producing the metallic material. The metallic material, which is, for example, an electromagnetic material (magnetic steel sheet), is obtained by subjecting a metallic material comprising a solid solution of a body-centered cubic (BCC) structure to hot compression at a temperature within a range where the solid solution is constituted only of a BCC phase, thereby distributing crystal axes <001> of the metal along the processed surface of the metallic material. The process is characterized by: heating the metallic material which is, for example, an Fe-Si alloy to a temperature in a range where the alloy is a solid solution constituted only of a BCC phase; and compressing this BCC-phase solid solution at a straining rate at which the solute atom atmosphere appearing in the BCC-phase solid solution governs movements for dislocation and at which grain boundaries are kept movable using, as a power therefor, strain energy that has accumulated in the grains, thereby distributing {100} planes in parallel to the processed surface.</p> |
