Abstract

The effects of Ar post-bombardment on the dissolution and reprecipitation of carbonitrides present in implanted 1020 low carbon steel are investigated using conversion electron Mössbauer spectroscopy (CEMS). The results are compared with similar experiments where samples of the same steel were post-bombarded with He. The experimental data show that the Ar is more efficient in the dissolution of precipitates and also more efficient in the precipitate retention at 450 °C, for the same peak concentration.
