摘要

摘要: 采用Thermo-Calc軟件分別計算硅在不同溫度Zn-50%Al-xFe-ySi(原子數分數)熔池液相中的溶解度及不同溫度Zn-30%Al-2%Fe-xSi(質量分數)熔池中開始形成τ₅渣相和FeAl₃渣相消失時該熔池中硅含量,采用平衡合金法測定Zn-50%Al-xFe-ySi合金液相中硅的溶解度和不同硅含量的Zn-30%Al-2%Fe-xSi合金的相平衡關系.當溫度分別為540、560、580、600和620℃時,硅在Zn-50%Al-xFe-ySi體系液相中的溶解度(原子數分數)計算值分別為0.82%、0.95%、1.11%、1.28%和1.47%,實驗結果與計算結果吻合很好.當熔池溫度分別為580、600和620℃時,在Zn-30%Al-2%Fe-xSi合金中剛開始出現τ₅相時所對應硅質量分數的計算值分別為0.6%、0.72%和0.84%,發生FeAl₃相消失對應的鋅池中硅質量分數的計算值分別為1.12%、1.22%和1.34%,實驗結果與計算預測結果基本一致.

Abstract: The solubility of silicon in a Zn-50%Al-xFe-ySi(in atomic fraction) molten bath and the content of silicon in a Zn-30%Al-2%Fe-xSi(in mass fraction) molten bath corresponding to the appearing of τ₅ slag phase and the disappearing of FeAl₃ phase were calculated at different temperatures using the Thermo-Calc software. At the same time,the solubility of silicon in liquid phase in the Zn-50%Al-xFe-ySi alloy and the phase equilibrium relationship of the Zn-30%Al-2%Fe-xSi alloy were experimentally determined by using the equilibrium alloy method. The results show that the calculated solubility of silicon in liquid phase in the Zn-50%Al-xFe-ySi system at 540,560,580,600 and 620℃ are 0.82%,0.95%,1.11%,1.28% and 1.47%,respectively,which agree well with the experimental data. When the temperature of the molten bath is 580,600,and 620℃,the calculated content of silicon in the Zn-30%Al-2%Fe-xSi alloy corresponding to the appearing of τ₅ phase in the molten bath is 0.6%,0.72% and 0.84%,and the values corresponding to the disappearing of FeAl₃ phase are 1.12%,1.22% and 1.34%,respectively,which agree basically with the experimental results.
