Abstract: Fe-Al intermetallics display notable application potential in the fields of aerospace, auto industry, energy exchanging 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.
