When the H atom dissolved in the tetrahedral interstices site, the differential charge density in bcc Fe (a), (d); bcc Fe–Cr (b), (e) and bcc Fe–Ni (c), (f). (a)–(c) Is the charge differential density diagram of the (001) slice. (g) Schematic diagram of the bcc Fe, bcc Fe–Cr, and bcc Fe–Ni lattice, where the gray shaded part is the (001) plane. The blue areas are where the charge density decreases, and the red areas are where the charge density increases.
