Abstract Amorphous layers produced at the surface of iron by B+ and C+ implantation (50 kV, 1×1018 ions cm−2) were analyzed by CEMS. The CEM spectrum of B+ implanted layer was composed of broad doublet and sextet. Spread hyperfine field distribution, P(H), indicates the formation of extremely disordered FeB layer. Annealing at 400°C brought about precipitation of FeB, which was converted to Fe2B by annealing at 500°C. The P(H) for C+ implanted iron was resolved to 3 subpeaks with H values of 11.0, 18.0 and 22.5 T. The amorphous FeC phase was strongly correlated to crystalline Fe5C2 and Fe2C, which precipitated at 300°C and were transformed into Fe3C at 500°C. The amorphous layer disappeared by annealing at 600°C.
