Abstract

The effects of constraint on the cleavage initiation fracture toughness of reactor pressure vessel (RPV) steels in the lower transition temperature region were investigated. The study was carried out by using relatively large cruciform fracture toughness specimens under varying degrees of biaxial loading. One of the materials used for the project was a plate of A533 grade B steel which was specially heat treated to result in a yield strength. During the testing phase to characterize the fracture the fracture toughness behavior of the plate with uniaxial three-point bend specimens, some relatively low fracture toughness values were observed.
