Abstract The effect of hydrogen on the bond structures.bond energy and electron distributions of intermetallic compound Fe3Al is investigated by Empirical Electron Theory of Solids and Molecules.The hydrogen embrittlement in Fe3Al is due to dissolving of hydrogen atoms to change the atomic state of Fe3Al resulting from the sharply reduction of lattice electrons,which cause the decrease of local metallicity,and the formation of severely anisotropic bond structures.At the same time,the hydrogen atoms may occupy the interstitial sites in Fe3Al.Correspondent.ZHANG Jianmin,postdoctoral,(Department of Superalloy,Central Iron and Steel ResearchInstitute,Ministry of Metallurgical Industry,Beijing 100081)
