建立了氧元素溶解到Ｔｉ６Ａｌ４Ｖ 合金中的热力学模型，并以此计算了ＩＳＭ（Ｉｎｄｕｃｔｉｏｎ ＳｋｕｌｌＭｅｌｔｉｎｇ） 熔炼过程中氧元素在Ｔｉ６Ａｌ４Ｖ 合金熔体中熔解度，分析了影响氧元素在Ｔｉ６Ａｌ４Ｖ 合金中溶解度的几个因素。结果表明，熔化室内氧气分压是决定Ｔｉ６Ａｌ４Ｖ 合金氧含量的主要因素，需要合理控制，同时提出了利用多次抽真空反充氩气以降低熔化室内氧气分压的方法，该方法在降低Ｔｉ６Ａｌ４Ｖ 合金中的氧含量方面取得明显效果．
The thermodynamic model of oxygen element dissolved in Ti6Al4V alloy was established. Based on this, the solubility of oxygen element in Ti6Al4V alloy melt during ISM (Induction SkullMelting) melting was calculated, and several factors influencing the solubility of oxygen element in Ti6Al4V alloy factor. The results show that the partial pressure of oxygen in the melting chamber is the main factor that determines the oxygen content of the Ti6Al4V alloy and needs to be properly controlled. Meanwhile, a method of using multiple vacuum back-filling argon gas to reduce the partial pressure of oxygen in the melting chamber is proposed. In the oxygen content achieved significant results.
