摘　　要：1400℃碳溶解度平衡实验测得：锰基Mn－Fe－P－C系碳的溶解度计算式为，Nc=0．2719－0．0940NFe－1．1954Np；整个锰铁熔体浓度范围，即从纯锰到纯铁范围，碳的溶解度计算式有，NC=0．2719－0．0945NFe和Nc==0．1959十0．1044NMn，通过热力学的推导和计算，得到以下一些热力学数据：①铁基体系，锰基体系。The Solubility of Carbon in Mn - based Mn- Fe- P -C systems was measured at 1400℃. The Solubility data Can be expressed as: Nc=0.2719 - 0.0940NFe- 1.1954Np. The Solubility of Carbon in Mn-Fe melts within the entire Concentrations can be calculated with the following formulas; Nc = 0.2719 - 0.0945NFe, and NC= 0.1959 + 0. 1044NMn- BY thermodynamical derivation and calculation, We obtaind some thermodynandcal data as follows: in Fe- based systems, NY=0.1959, lnγC = -0.670, in Mn - based systeInS,
