Abstract

Abstract

The radiation-induced segregation at precipitate-matrix interface in Fe-Cr-Mn austenitic alloy containing W and V was investigated by electron irradiation. The results show that the precipitates are identified as M23C6 type chromium-carbides. Cr, W and V are enriched, but Mn and Ni tend to be depleted at precipitate-matrix interface within grain.The morphology of precipitates occurred to change at and near the grain bou-boundaries, while Cr is depleted at precipitate-matrix interface.
The change of solute atom segregation behavior is directly related to segregation mechanisms.Two kinds of segregation phenomena of Cr concentration may be explained by the theory of radiation-induced segregation.
