鑄造鋁鎳鈷磁鋼的冶金質量分析

Metallurgical Quality Analysis of Casting Al-Ni-Co Magnet steel

  • 摘要: 應用綜合分析手段對航空電機轉子鋁鎳鈷磁鋼的碎裂行為進行了研究。通過對真空熔注與非真空熔注的鋁鎳鈷磁鋼的冶金質量分析,說明真空熔注的鋁鎳鈷磁鋼的質量與非真空熔注比較有明顯提高,使用的可靠性得到保障。

     

    Abstract: The rupture of the Al-Ni-Co magnet steels used aero-engine rotor is investigated with comprehensive analysis.Metallurgical quality analysis of Al-Ni-Co magnet steel shows that the quality of this steel under vacuum casting is better than that steel under atomosphere casting.The reliability n use for the former is secure. A lot of insclusion, such as Al2O3,TiN,i TiS, etc, ar.e formed resulting in the rupture of the alloy at work.
