摘要
The influence of C and Al content on phase transformation temperatures, i.e. the Al and A3 of Fe-rich alloys is investigated by dilatometric analysis. With the new set of experimental data, an updated thermodynamic description of the Fe-Al-C system is presented, using the thermodynamic data of the Fe-C, Fe-Al and Al-C systems, as well as the parameters for the Fe-Al-C ternary system optimized in this study. The good compatibility of the thermodynamic parameters with experimental data is demonstrated by several calculated vertical sections. A well reproduced vertical section of the Fe-Mn-Si-Al-C system is also presented according to the thermodynamic description of the lower order systems.
