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 a/o (atomic percent) Ni. The three-phase field wustite-spinel-alloy consists of wustite containing 0.51 a/o Ni, spinel containing 0.6 a/o Ni, and an alloy containing 79.6 a/o Ni. The three-phase field, spinel-nickel oxide-alloy, consists of nickel ferrite, nickel oxide containing 6.5 a/o Fe, and an alloy containing 99.5 a/o Ni. Tie lines in the spinel-alloy field were investigated in detail. Wustite-nickel oxide solid solutions exhibited nonideal behavior. (Author)
