<p>Precipitation hardening, austenitic type super-alloys containing 0.5 to 1.5 weight per cent silicon in combination with from 0.05 to 0.5 weight per cent of a post irradiation ductility enhancing agent selected from hafnium, yttrium, lanthanum and scandium, alone or in combination with each other. In addition, when hafnium or yttrium are selected, reductions in irradiation-induced swelling have been noted.</p> |
