Abstract:

The isothermal section of the Fe-Ni-O system at 1000 C has been defined by determining the compositions and structures of the equilibrated solid phases. Wustite can coexist with Fe-Ni alloys containing up to 79.6 ao atomic percent Ni. The three-phase field wustite-spinel-alloy consists of wustite containing 0.51 ao Ni, spinel containing 0.6 ao Ni, and an alloy containing 79.6 ao Ni. The three-phase field, spinel-nickel oxide-alloy, consists of nickel ferrite, nickel oxide containing 6.5 ao Fe, and an alloy containing 99.5 ao Ni. Tie lines in the spinel-alloy field were investigated in detail. Wustite-nickel oxide solid solutions exhibited nonideal behavior. Author
