Monocrystalline films of α-iron were implanted at room temperature with nitrogen to different doses. The transmission electron microscopy and conversion electron Mössbauer spectroscopy measurements have shown clearly that the two techniques are complementary in determining the nitride phases present in the implanted films. At low doses (lower than 5×10 16 ions/cm2) the α'-martensite is formed with the implanted nitrogen occupying octahedral sites. At higher doses (greater than 5×1016 ions/cm2) two phases which are more compact and progressively richer in nitrogen are observed, ε-Fe3N and ε-Fe2+xN.
