| Abstract |
The first-order approximated quasi-chemical model of Fe-base ternary system containing interstitial and substitutional solutes suggested by R. B. McLellan have been modified for dilute solid solutions with assumption that the interaction energy (εii) between interstitial solutes is zero. The interaction energy (Δε) between substitutional and interstitial atom and the diffusivities of interstitial elements in various substitutional compositions of Fe base system are calculated using published solubility of the system and diffusivity of Fe-interstitial binary data with above model. The nitrogen diffusivities in liquid Fe base binary alloys predicted by the above model with the assumption of ε_(NN)=0 agree with experimental results with some accommodation factor. |
