Fe-C-V、Fe-C-B熔体热力学性质

Thermodynamical Properties in Fe-C-V and Fe-C-B Melts

在1435,1485℃时分别测定了C在Fe-C-V和Fe-C-B熔体中的饱和溶解度。目的在于:用新的方法处理实验数据,获得熔体中溶质组元之间的活度相互作用系数。通过热力学推导和计算,得到熔体中组元之间某些重要的相互作用系数有:εVC=εVC=-11.96;eVC=-0.0542,eCV=-0.2443;εBC=εBC=14.16;eBC=0.2597和eBV=0.2344。

The saturated solubility of carbon in Fe-G-V and Fe-C-B melts was measured experimentally at 1435,1485℃ to obtain the activity interaction coefficients between components in these melts, A new method was used to treat experimental result~ By thermodynamical derivation and calculation, some important interaction coefficients between V C V G B C B C components in these melts were obtained as follows εC^V=εV^C=-11.96; eC^V=-0.0542, εV^C=-0.244 3; εC^B=εB^C=14.16, eC^B=0.259 7和eB^C= 0.2344
