为了提高B2型Fe-Co基合金的室温拉伸塑性，研究了添加微量Ni或Pd的合金的力学性能。新合金的屈服强度和抗拉强度都有显著的提高。Fe-Co-Ni合金在室温下具有超过10%的高延伸率。Co 50 Fe 40 Pd 10合金的抗拉强度为1250 MPa，总延伸率为16%。因此，Ni或Pd替代Fe-Co基合金是改善其室温延展性的非常有效的手段。[doi：10.2320/matertrans.M2012205]
We investigated the mechanical properties of B2-type Fe-Co based alloys containing minor amounts of Ni or Pd to improve their tensile ductility at room temperature. The yield and tensile stresses of the new alloys showed remarkable increases. Fe-Co-Ni alloys showed high total elongation of over 10% at room temperature. Co50Fe40Pd10 alloy displayed a tensile strength of 1250 MPa and a high total elongation of 16%. The substitution of Ni or Pd into Fe-Co based alloys is therefore an extremely effective means of improving their room-temperature ductility. [doi:10.2320/matertrans.M2012205]
