通过CALPHAD法,利用相关数据优化了Ti-Fe-Mn三元系,计算了1000℃等温截面图。同时还计算了Ti对Mn在1570℃时液相中活度的影响、TiMn2-TiFe2伪二元面、液相投影面和850℃与1150℃富Fe端BCCA2-FCCA1相平衡。计算结果与大部分实验结果吻合。
Ti-Fe-Mn ternary system was optimized by CALPHAD method using related data. The 1000℃ isothermal section was calculated. The effects of Ti on the activity of Mn at 1570℃ in Fe-Mn-Ti alloys, the vertical section of TiMn2-TiFe2, the liquidus surface projection, BCCA2-FCCA1 equilibrium in the Fe-rich alloys at 850℃ and 1150℃ were calculated. The results show that the present calculated results are in good agreement with most of experimental results.
