摘要

本文对铝对镍铬熔体中氧溶解度的影响进行了热力学分析。极低水平的铝实际上并不影响熔体中氧的浓度，这是由铬含量决定的。当所有合金的铝含量高于~ 0.01%时，它已经决定了氧在熔体中的溶解度。当铝含量为~ 0.2%时，氧浓度达到最小值，随着熔体中铬含量的增加，氧浓度也随之增加。Ni - 10%铬、镍铬合金- 20%铬和镍- 30%,它是2·三分,分别为7·三分和10 - 2。

THERMODYNAMICS OF OXYGEN SOLUTIONS IN ALUMINUM-CONTAINING Ni – Cr MELTS

Thermodynamic analysis of the effect of aluminum on the solubility of oxygen in Ni – Cr melts has been carried out. Aluminum at very low levels practically does not affect the concentration of oxygen in the melt, which is determined by the chromium content. When the aluminum content is above ~0.01 % for all alloys, it already determines the solubility of oxygen in the melt. The minimum values of the oxygen concentration are achieved with an aluminum content of ~0.2 %. With the increase of chromium content in the melt, the minimum oxygen concentration increases. For Ni – 10 % Cr, Ni – 20 % Cr and Ni – 30 % Cr alloys, it is 2·10–3, 7·10–3 and 10–2, respectively.
