Method for producing fe-co alloy rod

Abstract

Provided is a method for producing an Fe—Co alloy rod. This method for producing an Fe—Co alloy rod includes a heating and straightening step of applying tensile stress to a hot-rolled material of the Fe—Co alloy consisting of, in mass %, Fe+Co: 95% or more, Co: 25 to 60%, V: 1.70 to 2.10%, Mn: 0.01 to 0.15%, C: 0.008% or less, S: 0.01% or less, and remainder inevitable impurities as the balance, while heating the hot-rolled material of the Fe—Co alloy to a temperature of 500 to 900° C.

1 . A method for producing an Fe—Co alloy rod, comprising:
 a heating and straightening step of applying tensile stress to a hot-rolled material of an Fe—Co alloy consisting of, in mass %, 95% or more of Fe+Co, 25 to 60% of Co, 1.70 to 2.10% of V, 0.01 to 0.15% of Mn, 0.008% or less of C, 0.01% or less of S, and remainder being inevitable impurities, while heating the hot-rolled material to a temperature of 500 to 900° C. 
 
     
     
         2 . The method for producing the Fe—Co alloy rod according to  claim 1 , wherein no solution treatment is performed before performing the heating and straightening step.
