Some microstructural observations from solution annealed SA 316 SS after dual ion bombardment are presented which reveal a tendency for cavity alignment and enhanced cavity growth and coalescence under specific helium damage and temperature conditions. It is suggested that this excessive swelling is intimately linked with acicular precipitate formation which induces cavity alignment. (FS)
