Abstract
The tensile properties of 304L stainless steel have been investigated after low temperature ( less than or equal to 250 degrees C) irradiation with 80 0 MeV protons at the LANSCE accelerator to a maximum fluence of 3 x 10(25) p/m(2), corresponding to a displacement dose of about 8.5 dpa. The results showed irradiation hardening and a concomitant loss of ductility with incre asing proton fluence. Subsequent SEM observation revealed that the fracture mode changed from typical ductile to partial intergranular brittle after i rradiation. (C) 1999 Elsevier Science B.V. All rights reserved.
