摘要
研究了Ni/N/Ti系合金的真空感应熔炼过程,通过分析氮含量的变化,计算了镍基高温合金中钛对氮的相互作用系数值为-0.38,氮的活度系数为0.174,氮的溶解度为0.0003%。
The process of VIM smelting Ni/N/Ti alloy was studied. By analyzing the change of nitrogen content, the interaction coefficient of titanium with nitrogen is-0.38 by calculated in the nickel-based superalloy, the activity coefficient is 0.714, and the solubility of nitrogen is 0.0003%.
