Abstract

Abstract

Behaviour of grain boundaries segregation and precipitate in Fc-Cr-Mn and Fe-Cr-Mn-W-V alloys were investigated during thermal againg and irradjation by electron beam.
Experiments show that Cr, Mn are depleted on grain boundaries during thermal aging in Fe-Cr-Mn-W-V alloy. It is depended on chemical composition of M₂₃C₆ type chromium-carbides. Cr and Mn in both alloys mentioned above are depleted on grain boundaries during irradiation. It is depended on concentration of radiation-induced cavity and void swelling. Radiation-induced segregation effects on chemical composition of precipitate M₂₃C₆ in both alloys.
