J-R curves of an austenitic stainless steel in solution annealed and c
old worked conditions were obtained using miniaturized fracture toughn
ess specimens and standard compact tension specimens. Results indicate
that the specimen size effect for the cold worked steel was small. J(
Q) values of irradiated miniaturized specimens agreed well with those
of cold worked specimens with similar yield stress levels. This sugges
ts that the irradiation induced degradation of the fracture toughness
is mainly dependent upon the irradiation hardening.
