Abstract
The effects of Kr post-bombardment on iron-carbonitrides produced by N -implantation in a low carbon steel are studied by means of conversion electron Mossbauer spectroscopy, nuclear reaction analysis and Ruther ford backscattering techniques. The results show that the Kr bombardme nt strongly affects the thermal behavior of the precipitates, raising their temperature of dissolution. It is suggested that Kr-vacancy comp lexes are responsible for a nitrogen inhibited diffusion, which turns out in a retention of the iron-carbonitrides at higher temperature.
