Abstract
The creation of defects and radiation-induced segregation (RIS) in sin gle crystals of type 304 stainless steel, 1.6 MeV He irradiated up to 2.5 x 10(17) cm(-2) at RT, has been investigated by using a combinatio n of RES and PIXE with channeling (RBS-C and PIXE-C). From the RBS-C, it is found that radiation-induced defects for [110] orientation incre ased more slowly with irradiation dose from those for the [100] and [1 11] orientations. The PIXE-C measurements show that Si atoms segregate to the (100), (110) and (111) surfaces and S atoms seem to enrich sli ghtly in the (100) and (110) surfaces during 1.6 MeV He ion irradiatio n. It is the first time that the phenomenon of radiation-induced segre gation is observed in stainless steels at room temperature irradiation .
