Fe-Al金属间化合物具有良好的抗氧化、抗硫化腐蚀性能以及高温结构性质,而且质轻价廉,在航空航天、汽车工业、能量转换系统、过滤材料等领域具有广阔的应用前景,但在室温下易发生环境脆化,这也是其未能得到大规模应用的主要原因.本文在介绍 Fe-Al金属间化合物特性的基础上,重点综述了 Fe-Al金属间化合物氢脆行为及其机制的实验和理论研究进展,提出了今后的研究方向.%Fe-Al intermetallics display notable application potential in the fields of aerospace,auto industry,energy exchan-ging system,filteration materials,etc.Owing to their favorable oxidation resistance and sulfidation resistance as well as high-tempe-rature performance.However,the poor ductility of intermetallics is the biggest obstacle for their large-scale practical application.In this paper,we provide an overview upon the research endeavors in the past decade about the hydrogen embrittlement behavior and the corresponding mechanism,and put forward the points which deserve consideration in the future studies.
