Effect of cold work on swelling and void microstructures was investiga
ted for Fe-15Cr-20Ni alloy irradiated with 180 keV protons to 10 dpa a
t 773-873 K (500-600 degrees C). The He preinjection level was 10 appm
at room temperature. The introduced dislocations in Cold-worked (CW)
specimen recovered thoroughly during the irradiation for all the irrad
iation temperatures. Although there was no significant difference in v
oid microstructure between solution-annealed (SA) and CW specimens at
773 K, larger and fewer voids were observed in CW specimens at tempera
tures above 823 K. The amount of swelling was similar in both SA and C
W specimens at all the irradiation temperatures. Cold work treatment s
eems to be less effective in controlling swelling of the He preinjecte
d Fe-15Cr-20Ni alloy in the present proton irradiation. (C) 1998 Elsev
