摘要: 用Mo反应室密封,Pb蒸气-Fe液平衡法研究了1300—1400℃范围内Fe-C-Pb溶液的热力学性质,通过测定C对Pb在Fe液中的溶解度的影响,求得C与Pb的一阶、二阶活度相互作用系数与温度的关系: e_(Pb)~C=9205(1/T)-4.578;γ_(Pb)~C=-1047(1/T)+0.512 用石墨坩埚石英管真空密封装置,Pb蒸气-Fe液平衡法测得1300℃时Fe-C_(sat)-Pb-Ce溶液中Ce与Pb的活度相互作用系数:e_(Pb)~(ce)=-2.11;e_(ce)~(Pb)=-1.43.

Abstract:The thermodynamic properties of Fe-C-Pb liquid solution in the tem-perature range 1300--1400℃ have been studied using the equilibrium method betweenPb vapour and liquid Fe in sealed Mo reaction chamber. The temperature depend-ence of the first and second order interaction coefficients between C and Pb areobtained as follows: e_(Pb)~C=9205(1/T)-4.578, γ_(Pb)~C=-1047(1/T)+0.512. The thermody-namic preperties of Fe-C_(sat)-Pb-Ce liquid solution at 1300℃ have been determinedusing the equilibrium method between vapour and liquid in a graphite cruciblesealed in a vacuum quartz tube. The interaction coefficients between Ce and Pb arederived to be: e_(Pb)~(Ce)=-2. 11, e_(Ce)~(Pb)=-1.43.
