铸造铝镍钴磁钢的冶金质量分析

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

摘要: 应用综合分析手段对航空电机转子铝镍钴磁钢的碎裂行为进行了研究。通过对真空熔注与非真空熔注的铝镍钴磁钢的冶金质量分析,说明真空熔注的铝镍钴磁钢的质量与非真空熔注比较有明显提高,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.
