在Ｆｅ３Ａｌ中添加适量的Ｃｅ可以显著提高合金的室温强度和塑性，分析表明，这是由于Ｃｅ的加入改变了合金表面氧化层的组成，抑制或推迟了Ａｌ和环境水汽的反应，并且在基体中形成了许多弥散分布的富Ｃｅ相。
The addition of proper amount of Ce in Fe3Al can significantly improve the room temperature strength and plasticity of the alloy. The analysis shows that the addition of Ce alters the composition of the oxide layer on the surface of the alloy, restrain or delay the reaction of Al with the ambient water vapor, A number of dispersed Ce-rich phases were formed.
