METHOD FOR MANUFACTURING Fe-Co-BASED ALLOY ROD, AND Fe-Co-BASED ALLOY ROD

摘要

Provided are an Fe-Co-based alloy rod and a method for manufacturing same, whereby excellent magnetic properties can be reliably obtained.　The method for manufacturing an Fe-Co-based alloy rod comprises a heating straightening step for applying tensile stress to a hot-rolled material of an Fe-Co-based alloy while heating the hot-rolled material to a temperature of 500-900°C. Preferably, ohmic heating is used as a heating means in the heating straightening step. In addition, the Fe-Co-based alloy rod has 20% or more by area ratio of crystal grains having a grain orientation spread (GOS) value of at least 0.5°.
