Abstract
Along with higher performance of products, materials are also required to achieve both a high strength and favorable magnetic properties according to applications of products. Therefore, the present invention provides an Fe—Co-based alloy bar which enables both a high strength and favorable magnetic properties to be achieved. An Fe—Co-based alloy bar contains 30% to 80% of crystal grains having a grain orientation spread (GOS) value of 0.5° or more in terms of an area ratio, and having an average crystal grain size number of more than 8.5 and 12.0 or less. The Fe—Co-based alloy bar of the present invention has a high 0.2% yield strength after magnetic annealing so that it can support various high-strength applications.
