摘　　要：采用金相、扫描电镜和X射线衍射等分析手段,研究稀土铝合金化对穿孔顶头组织性能及氧化膜的影响。研究结果表明,稀土铝合金化可提高材料的硬度、强度及氧化膜的致密度。The effects of RE-Al alloying on the microstructure and properties and the oxide film of the piercing plug were studied by metallographic examination,SEM and X-ray diffraction.The results show that RE-Al alloying can improve the hardness,the strength and the oxide film density of the piercing plug.
