The compositional analysis in the irradiated regions including grainboundaries was performed. The results show that there are many common featuresof irradiation behavior in the Fe-Cr-Mn and Fe-Cr-Ni systems while there are somesignificant differences. In the Fe-Cr-Mn alloy systems void swelling was remarka-bly suppressed and at the same time the radiation-induced segregation was also re-tarded, furthermore, the segregation was strongly retarded in Fe-15Cr-15Mn alloycontaining small amount of W and V. The results also show that Ni replaced byMn does not in general confer immunity from either swelling or phase instabilities.The phase instability is due to the different diffusion behavior of Ni and Mn inresponse to the operation of the inverse-Kirkendall effect. Fe segregates to the mi-crostructural sinks in the Fe-Cr-Mn alloys. The segregation of Fe often leads tothe formation of ferrite. This fact is beneficial to reduce the swelling rate andsegregation on the grain boundaries.
