Gibbs free energy evaluation of the FCC(γ) and HCP(ε) phases in Fe-MN-Si alloys
TLDR
In this article, the Gibbs free energy as a function of temperature of the fcc(γ) and hcp(e) phases in the Fe-Mn-Si system is evaluated by the application of the general model for predicting thermodynamic properties for ternary systems from binary ones.Abstract:
The Gibbs free energy as a function of temperature of the fcc(γ) and hcp(e) phases in the Fe-Mn-Si system is evaluated by the application of the general model for predicting thermodynamic properties for ternary systems from binary ones, suggested by Chou and by the utilization of the available data from binary Fe-Mn, Fe-Si and Mn-Si systems and the SGTE DATA given by Dinsdale. The calculated result seems reasonable as compared with the experimental data.read more
