摘　　要：概述了Fe-Al金属间化合物的基本特性,简述了几种改善Fe-Al金属间化合物脆性的常规方法。详细介绍了Fe-Al金属间化合物作为高温耐磨耐蚀涂层和高温气体净化多孔材料的研究新方向,以及借助先进的定向凝固技术制备Fe-Al-Ta金属基复合材料的研究新进展,指出了当前Fe-Al金属间化合物的研究领域存在的问题及今后的主要发展方向。In this paper, the basic characters of the Fe- A1 intermetallic compound were reviewed and several effective methods to improve the brittleness were mainly introduced. Besides, the new research trends of wear and corrosion resistance coating material at high temperature and high temperature gas purification porous material were introduced. Furthermore, a special attention was paid to the new research progress of Fe-A1-Ta composites prepared by new directional solidification technologies. In addition, the inadequacies in the previous works were dis- cussed, and the suggestions to further research works in this area were proposed.
