摘要： PURPOSE:To produce the titled alloy sheet excellent in uniaxial anisotropy by a method wherein an Fe-Co-Si alloy sheet prepared by a super quenching method is heat treated in an oxidizing gas atmosphere to impart a uniaxial anisotropy to the sheet, and then the sheet is heat treated in a non-oxidizing atmosphere at a temperature of not higher than the melting point of the alloy. CONSTITUTION:An alloy base material consisting of 10-20wt% of Co, 8-16wt% of Si and the balance of Fe is melted, and the molten alloy material is jetted from a nozzle onto twin rollers rotating at a high speed or the like to form a belt-shaped sheet through quenching and rolling. The alloy sheet thus obtained is then heat treated in an oxidizing gas atmosphere such as air or O2 at a pressure of 0.2-0.3 Torr to cause the rolled surfaces of the sheet to become uniaxially anisotropic. The heat-treated alloy sheet is then heated to a temperature of not higher than the melting point of the alloy in a non-oxidizing atmosphere such as H2 or Ar gas. As a result, an Fe-Co-Si based high-permeability alloy sheet containing Fe as a major component and having soft magnetic properties with excellent uniaxial anisotropy is obtined.
