摘要
用新方法处理了文献报道的1400℃C饱和的Mn-Fe-P-C系的实验结果。热力学推导与计算结果表明,Mn-Fe-P-C系(XFe=0.0785～0.1209,XP=0.0010～0.0085)中C的饱和溶解度、lnγC和lgfC的计算式分别是-lnXC-9.8543XC=1.2373XFe+17.2820XP-1.3754,lnγC=-1.4014+9.8543XC+1.2373XFe+17.2820XP+0.0260和lgfC=0.1532犤%C犦+0.0055犤%Fe犦+0.1153犤%P犦+0.0150。lnγC和lgfC计算式中的0.0260和0.0150分别是Wargner式中二次及二次以上的项对lnγC和lgfC的影响。
A new method was used to treat the experimental results of Mn-Fe-P-C system (XFe= 0.078 5～ 0.120 9,XP=0.001 0～ 0.008 5)saturated with C rep orted in reference.Thermodynamical derivation and calculation show that the calc ulation formulas of C solubility,ln? C and lgfC are respectively-lnXC-9.85 4 3XC= 1.237 3XFe+ 17.282 0XP-1.375 4, ln? C=-1.401 4+ 9.854 3XC+ 1.237 3 XFe+ 17.282 0XP+ 0.026 0 and lgfC=0.153 2+ 0.005 5+ 0.115 3+ 0.015 0.The 0.026 0 and 0.015 0 in the above formulas are respectively t he effects of second order and above second order terms in Wargner formulas on ln? C and lgfC.
