摘要：

Samples of Ti-modified stainless steel alloy have been irradiated using 315 KeV Ar9+ ion to varying doses resulting in high dpa levels from 100 to 400. The variation of the secondary phase present in the sample as a function of irradiation dose has been characterised using Grazing Incidence X-ray Diffraction measurements. Energy Dispersive X-ray mapping of the irradiated volume has also been carried out to see the variation in the spatial distribution of the major alloying elements in the un-irradiated and irradiated samples as a function of dose. The study reveals that there is enhancement of secondary phases due to irradiation, which at very high doses re-dissolves into the matrix.
