摘要
研究了使用 Ca O坩埚在 VIM法精炼 Ni基高温合金过程中 N的变化规律及加 Al对脱 N的影响 ,初步分析了脱 N的影响因素及机理。
The changing law of N element during the process of VIM refining Ni base superalloy by using CaO crucible and the influence of aluminium to denitrogenation are studied .The influence factors and principles on denitrogenation are preliminary discussed.
