Abstract

A thermodynamic assessment of the Bi-Mn binary system was conducted using the CALPHAD approach. Consistent thermodynamic descriptions, which agreed well with the selected experimental data, were obtained using a sub-regular solution model for solution phases and a line-compound model for intermetallic compounds. There are several discrepancies between the phase diagram drawn in a previous study and that calculated in this study. The two-phase separation that appeared in the previous phase diagram was not calculated and the calculated liquidus boundaries at around 1000K changed smoothly compared with that in the previous diagrams. From the viewpoint of thermodynamic consideration, the calculated phase diagram presented in this study is reasonable.
