摘要
用碳饱和法研究了1450℃时Mn-Fe-C系和Mn-V-C系有关的热力学性质,得到Mn-Fe-C系:Xc:0.27 994-0.10 044 XFe,lnγc0=-1.4 558,εcc=9.896,εcFe=0.359,ρcFe=0.064,εcFe=1.354,C的活度系数表达式为lnγc=-1.4 558+9.896 Xc+1.354 XFe;Mn-V-C系:Xc=0.2771+0.3395 Xv,εcv=-1.225,ρ=0.751,εcV=-4.584,C的活度系数表达式为lnγc=-1.4558+9.896 Xc-4.584 Xv.
This paper summarizes the thermodynamic properties of Mn - Fe - C and Mn - V - C systems obtained by measuring the saturated solubility of carbon in the systems at 1 450℃ respectively. The following results were obtained: XC = 0.27 994-0.10 044 XFe, lnγC0= -1.4 558, εCC = 9.896, εcFe = 0.359,ρcFe = 0.064,εcFe = 1.354, and lnγc = -1.4 558 + 9.896 Xc+1.354 XFefor the Mn-Fe-C system; Xc= 0.2 771 + 0.3 395 Xv,εcv= -1.225, ρcv = 0.751, εcV= -4.584, and lnγc= -1.4558 + 9.896 Xc-4.584 Xv for the Mn-V-C system.
