本文通过真空熔炼和真空雾化工艺制备了MCrAlY合金铸锭及粉末，研究了真空熔炼过程中保护气压力和保温时间对MCrAlY合金铸锭中Y的收得率的影响以及上述两种工艺在不同Y配入量下Y的残余含量的变化。结果表明，真空熔炼过程中Y的收得率随保护气体压力和保温时间的增加而减小；Y在真空雾化工艺的雾化过程中损失较小，两种工艺在相同的Y配入量下具有接近的Y残余含量。
本文通過真空鎔煉和真空霧化工藝製備瞭MCrAlY閤金鑄錠及粉末，研究瞭真空鎔煉過程中保護氣壓力和保溫時間對MCrAlY閤金鑄錠中Y的收得率的影響以及上述兩種工藝在不同Y配入量下Y的殘餘含量的變化。結果錶明，真空鎔煉過程中Y的收得率隨保護氣體壓力和保溫時間的增加而減小；Y在真空霧化工藝的霧化過程中損失較小，兩種工藝在相同的Y配入量下具有接近的Y殘餘含量。

In this paper, MCrAlY alloy ingot and powder was prepared by vacuum melting and vacuum melting gas atomization process. The effect of shielding gas pressure and holding time on the Y element yielding rate of MCrAlY alloy ingot during the vacuum melting process and the variation of Y residual contents with different initial Y adding amount in the above two processes were studied. Results showed, the Y element yielding rate was decreased as the shielding gas pressure and holding time increased;Y residual contents were similar under the same initial Y adding amount for above two different processes, for the reason that the loss of Y element was low in the atomization process.
