Abstract
Thermodynamic analysis of the effect of silicon on the solubility of oxygen in Fe – Co – Cr melts has been carried out at 1873 K. Silicon has a sufficiently high deoxidizing ability in Fe – Co – Cr melts. Silicon at low contents practically does not affect the concentration of oxygen in the melt, which is determined by the chromium content. With a higher content of silicon after changing the mechanism of interaction process of chromium and silicon with oxygen, when silicon already determines the solubility of oxygen in the melt, the oxygen concentration decreases.
在1873 K时，对硅对Fe - Co - Cr熔体中氧溶解度的影响进行了热力学分析。硅在Fe - Co - Cr熔体中具有足够高的脱氧能力。低含量的硅实际上不影响熔体中氧的浓度，这是由铬含量决定的。随着硅含量的增加，铬、硅与氧的相互作用机理发生改变后，当硅已经决定了氧在熔体中的溶解度时，氧浓度降低。
