Radiation-induced spinodal-like decomposition of Fe-Cr-Ni alloys and its influence on electropolishing of microscopy disks

Technical Report ·
OSTI ID:7074401

The object of this effort is to provide an understanding of the factors which control the radiation-induced evolution of microstructure in structural alloys. Scanning electron microscopy was used as a tool to investigate the dependence on nickel content of radiation-induced spinodal-like decomposition in Fe-15Cr-XNi alloys. It appears that the relative resistance to swelling observed in the Invar compositional regime at 510{degree}C is concurrent with spinodal-like decomposition. The influence of this phenomenon in prolonging the loop-dominated phase of dislocation evolution and also suppressing the onset of accelerated void growth has not yet been determined.
