Abstract
The austenitic stainless steels of type 304 and type 316 and the preci pitation hardened type 630 stainless steel were irradiated to doses ra nging from 5 x 10(24) to 1.2 x 10(26) n/m(2) at 323 K in the Japan Mat erials Testing reactor (JMTR). Tensile and fracture toughness tests ha ve been carried out at 293 K. Type 304 and 316 steels in the solution annealed condition hardened by irradiation to about 700 MPa. Fracture toughness values for these steels decreased with dose. Only a small ha rdening occurred after irradiation for cold worked type 304 and precip itation hardened type 630 steels. The effect of irradiation on the fra cture surfaces was small.
