Implantation Radiation Damage after Effects

Abstract

γ (fcc)→α (bcc) phase transformation in type 304 stainless steel has been observed after irradiation of He+ and H+ ions up to fluence levels of 1017 and 1019 ions/cm2, respectively. Depth selective conversion Mössbauer spectroscopy and surface-sensitive X-ray diffractometry were employed to study the effect of irradiation. It is shown that the amount of the ion induced phase is highly sensitive to the fluence, the ion species and depth from the surface. It is worth noting that H+ ion irradiation is rather ineffective in inducing the transformation.
