MANUFACTURE OF SOFT MAGNETIC MOLDED BODY OF HIGH PERMEABILITY AND HIGH SATURATION MAGNETIC FLUX DENSITY

摘要

PROBLEM TO BE SOLVED: To provide a soft magnetic molded body comprising Fe base alloy of low cost which has both high saturation magnetic flux density and high permeability and is easily manufactured.;SOLUTION: Manufacturing of the soft magnetic molded body includes a process for manufacturing a thin band which can be bent 180° and has a multiphase system in which Fe radical alloy composition in molten state is quench-solidified so that α-Fe crystal phase whose average particle size is 50nm or less is dispersed in an amorphous phase, and a process for heating the thin band up to the temperature higher than the crystallizing temperature of α-Fe crystal phase.;COPYRIGHT: (C)2006,JPO&NCIPI
