摘要：
A high strength and creep resistant soft magnetic Fe—Co alloy includes, in weight %, Fe and Co such that the difference between the Fe and Co is at least 2%, at least 35% Co, and 2.5%≦(V+Mo+Nb), wherein 0.4%≦Mo and/or 0.4%≦Nb. This alloy can further include B, C, W, Ni, Ti, Cr, Mn and/or Al. A vanadium-free high strength soft magnetic Fe—Co alloy includes in weight %, Fe and Co such that the difference between the Fe and Co is at least 2%, and at least 15% Co, the alloy further satisfying (0.1%≦Nb and 0.1%≦W) or 0.25%≦Mn. This alloy can further include B, C, Ni, Ti, Cr and/or Al.
