摘要
According to the ion and molecule coexistence theory, the activity model of Fe-Si-B ternary system was es- tablished, and the influence of ratio ：Csi/XZe, boron content and temperature, etc. on the activity of the melt com- pound was investigated. The results show that the FeB activity is high in the liquid iron, when Xsl/XFo is 0. 5 ; the ac- tivity of boron increases with increasing the boron content for different contents of xe and xs, and the activity of boron at the ratio xFo = 0.4 is about one order of magnitude higher than that for the XFo = 0. 8; The activities of the melt compound were also affected by temperature, but the influencing extent was little. The equal activity diagrams of silicon and boron were drawn for the first time according to the model results.
