Abstract
A method for improving the post-irradiation ductility is described which prises a solution heat treatment following which the materials are cold worked. They are included to demonstrate the beneficial effect of this treatment on the swelling resistance and the ductility of these austenitic precipitation hardenable alloys.
Claims3
The method of improving the post-irradiation ductility of precipitation hardenable alloys, the steps comprising solution heat treating the alloys at a temperature within the range between about 950.degree. C. and about 1150.degree. C. and thereafter cold working the alloys to effect a reduction in cross-sectional area of between about 10% and about 60%.
