摘要
根据含化合物金属熔体的共存理论,Fe-La相图、Fe-O相图,及相关文献的研究成果,确定了Fe-La-O金属熔体的结构单元,进而推导了各组元作用浓度的计算模型.研究表明,计算的作用浓度与相应的实测活度相符合,从而证明所得模型可以反映Fe-La-O金属熔体的结构本质,同时说明计算过程中引用的La2O3的平衡参数"ΔG°=-75 380+17.60T"是准确的.
The computational model of action concentration of Fe-La-O system was obtained according to the coexistent theory about metal melt structure containing compounds and the research results of related iliteratures were referenced.The computed action concentration accords with the relevant measured activity and the phase diagrams of Fe-La and Fe-O,which proves that the model can express the structural quality of Fe-La-O metal melt.At the same time,it is shown that the referenced standard free energy of formatio...
