| 英文摘要 | Raoultian activity coefficients gamma(0)(C) of C in infinitely dilute Fe-C binary melts at temperatures of 1833, 1873, 1923, and 1973 K have been determined from the converted mass action concentrations N-C(') of C in Fe-C binary melts by the developed AMCT-N-i model based on the atom-molecule coexistence theory (AMCT). The obtained expression of gamma(0)(C) by the developed AMCT-N-i model has been evaluated to be accurate based on the reported ones from the literature. Meanwhile, three activity coefficients gamma(C), f%,C, and f(H,C) of C coupled with activity a(R,C) or a%,C or a(H,C) have been obtained by the developed AMCT-N-i model and assessed through comparing with the predicted ones by other models from the literature. The first-order activity interaction coefficients epsilon(C)(C), e(C)(C), and h(C)(C) related to gamma(C), f%,C, and f(H,C) are also determined and assessed in comparison with the reported ones from the literature. Furthermore, the integral molar mixing thermodynamic functions such as Delta H-mix(m,Fe) C, Delta S-mix(m,Fe) C, and Delta(mix)G(m,Fe) C of Fe-C binary melts over a temperature range from 1833 to 1973 K have been determined and evaluated to be valid based on the determined ones from the literature. |
