A Cooperative Study for the Evaluation of Crack Arrest Toughness of RPV Materials in Japan

Source

Results are presented from an investigation of crack arrest toughness Ka, on ASTM A533B Class 1 and A508 Class 3 steels using ASTM-proposed specimens and ESSO specimens. The results show that the values of Ka, measured in accordance with the ASTM test method, increased with an increase in test temperature, and that the size requirements in the method were appropriate to obtain valid values of plane-strain crack arrest toughness KIa. It was also found that the ASTM and ESSO tests lead to about the same crack arrest toughness values when applied to large specimens of the same size. The lower bound of KIa data was significantly under that of KIc data on the test materials, though both bounds were well over the American Society of Mechanical Engineers (ASME) KIR curve.
