Abstract

The small specimen test technique and the less-specimen-consumed test method for evaluating the fracture toughness are highly required in the nuclear field. In the present study, the fracture toughness properties of the F82H steels with the size of 1/4 CT and 1/6 CT were evaluated by the master-curve approach. Comparing the 1/4 CT and 1/6 CT data with that obtained by the 1 CT specimen, it shows no substantial effect of the specimen size on the evaluation of the fracture toughness by the master-curve approach.
