Abstract
Samples of AISI 304 and 316 stainless steels, initially in austenitic (first set) and martensitic states (second set) and alpha-Fe (third se t), were implanted with 180 keV C-12- to a dose of 10(17) atoms/cm2 at room temperature. Surfaces were examined by SEM (scanning electron mi croscopy) and the crystalline-phase fractions were estimated through C EMS (conversion electron Mossbauer spectroscopy). Different grades of etching were produced by sputtering during the implantations on the st ainless steel samples depending on the previous crystallographic state s. CEMS data reveal the gamma --> alpha' transformation in the initial ly martensitic samples and no noticeable modifications as a result of the implantation on a-Fe and austenitic samples.
