Tungsten-inert-gas weld joints prepared from the IEA heat of F82H were irradiated with 10.5 MeV Fe ions and 1.05 MeV He ions at 450 °C. Transmission electron microscopy observation revealed a marked cavity growth up to 30 nm at 50 dpa in the over-tempered portion of the heat-affected zone (HAZ), while cavities in the quenched portion of HAZ remained smaller (up to 10 nm). Base metal results also showed that a specimen tempered at 780 °C contained larger cavities than those tempered at 750 °C. Cavities in cold-worked specimens were the smallest. Initial dislocation densities in F82H, which are affected by heat treatment and/or mechanical treatment, dominate the cavity growth. © 2002 Elsevier Science B.V. All rights reserved.
