Abstract

We investigated the mechanical properties of B2-type FeCo 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. FeCoNi alloys showed high total elongation of over 10% at room temperature. Co50Fe40Pd10 alloy displayed a tensile strength of 1250MPa and a high total elongation of 16%. The substitution of Ni or Pd into FeCo based alloys is therefore an extremely effective means of improving their room-temperature ductility.
