Abstract

Model solute distribution studies have been performed in N-implanted Fe. Concentration-verses-depth profiles have been determined by secondary ion mass spectroscopy for Fe implanted to low fluences with isotopes 13C at 190keV and 15N at 180keV followed by 14N to high fluences. At N fluences greater than 2.5 × 1017 /cm2 dramatic changes in the 13C and 15N profiles are observed. It is proposed that these changes are caused by the lattice dilation due to precipitation of iron nitrides.
