Calculation of Fe-Ni-O Ternary Phase Diagram
Abstract
Fe-Ni-O에서 존재하는 여러상들의 자유에너지에 대한 수식적 표현을 검토하였다. 이들중 spinel상은 Schmalzried등이 제안한 식으로, 그리고 ε상과 ι상은 아정규용액 모형으로 잘 설명되었다. 이들 용액모형을 이용하여 계산된 1273K 등온단면도와 상안정도는 실험자료와 잘 부합하였다.
The analytical expressions for the free energies of various phases existed in the Fe-Ni-O system were dicussed. Among them, the spinel phase is well fitted in the expression proposed by Schmalzried et al., and the εand the ιphases are well described by the subregular solution model. The isothermal section and stability diagram which are calculated using these solution models at 1237K are in good agreement with the experimental data.
