Title:
FE-CO ALLOY BAR STOCK
Document Type and Number:
WIPO Patent Application WO/2023/042278
Kind Code:
A1
Abstract:
As products become higher performance, materials themselves will need to have both high strength and favorable magnetic properties to match the uses of the products. Provided is an Fe-Co alloy bar stock that makes it possible to achieve both high strength and favorable magnetic properties. The Fe-Co alloy bar stock is, by area ratio, 30%–80% crystal grains that have a grain orientation spread (GOS) value of at least 0.5°, and the Fe-Co alloy bar stock has an average crystal grain size number of above 8.5 but not above 12.0. The Fe-Co alloy bar stock also has a high yield stress of 0.2% after magnetic annealing to handle various high-strength uses.
