通过适当的非真空冶炼＋电渣重熔工艺，制备了含Ｃｒ的Ｆｅ３Ａ１基金属间化合物合金． 实验发现，选择适当的热输入工艺参数，电渣重熔过程极大地降低了Ｆｅ３Ａ１基金属间化合物合 金中的Ｓ，Ｏ，Ｈ，Ｐ等杂质元素的含量，改善了析出相的大小与分布．铸锭具有良好的热加工性能， 经锻造和中温热机械处理后，纵向室温延伸率分别超过８％和１０％，屈服强度超过４００ＭＰａ，断 裂强度达到 ７００ ＭＰａ，力学性能与同类真空冶炼大体积材料的性能相当．
The Cr-containing Fe3Al-based intermetallic compound alloy was prepared by appropriate non-vacuum smelting + ESR process. The experiment found that the electroslag remelting process greatly reduced the content of S, O, H, P and other impurity elements in the Fe3A1-based intermetallic compound alloy and improved the size and distribution of the precipitated phase by selecting appropriate heat input process parameters. The ingot has good hot workability. After forging and medium temperature mechanical processing, the longitudinal room temperature elongation exceeds 8% and 10% respectively, the yield strength exceeds 400 MPa and the breaking strength reaches 700 MPa. The mechanical properties are similar to those of the same kind of vacuum smelting large volume The performance of the material is equivalent.
