Two phase ferromagnetic composites in Co-Zr and Co-Zr-Fe systems containing anti-phase domain imparting very high strength

Two compositions, namely Co-19%Zr and Co-8%Fe-19%Zr (all in atomic percentage), both of which contain the magnetic phases Co11Zr2 and Co23Zr6, with Fe substituting Co in the ternary alloy. The TEM micrographs demonstrate presence of the antiphase domain of the composition of 11:2 and 23:6 binary and ternary phases in the alloy.
