Title:
FE-CO-BASED ALLOY ROD MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/042279
Kind Code:
A1
Abstract:
Provided is a Fe-Co-based alloy rod material which can achieve excellent magnetic properties reliably. The Fe-Co-based alloy rod material contains crystal grains having a GOS (Grain Orientation Spread) value of 0.5° or more at an area ratio of more than 80%, in which the difference between the area ratio of crystal grains having a GOS value of 0.5° or more as observed in a cross-sectional surface taken in a direction perpendicular to the axis of the rod material and the area ratio of crystal grains having a GOS value of 0.5° or more as observed in a cross-sectional surface taken in a direction of the axis of the rod material falls within 10%. Preferably, the average crystal grain size number is 6.0 to 8.5 inclusive.
