...Jong-Min Kim; Seok-Min Hong; Min-Chul Kim; Bong-Sang Lee The standard master curve (MC) approach has a major limitation in that it is only applicable to homogeneous datasets. In nature, steels are macroscopically inhomogeneous. Reactor pressure vessel (RPV) steel has different fracture toughness...

...Naoki Miura; Yasunori Momoi; Masato Yamamoto The Master Curve approach using miniature C(T) specimens with 4 mm thickness is promising for directly determining the reference temperature of reactor pressure vessel (RPV) steels because they can be taken from the broken halves of the Charpy specimens...

... properties for this class of steel to provide a more definite database for use in structural and defect analyses of pressurized components, including pressure vessels and storage tanks. Another purpose is to determine the reference temperature, T 0 , derived from the Master curve methodology which defines...

... investigation is required using the extensive fracture toughness database together with expertise in this field. In this study, we first examined the applicability of the Master Curve approach to the typical national RPV steels using a fracture toughness database. The reference temperature...

... Jc median values versus T-T 0 from tests of Midland beltline weld showing that the results follow the master curve shape for both unirradiated and irradiated conditions ( 86 87 ) Comparison of master curve reference temperature T 0 values from compact and PCVN...

...Kim R. W. Wallin; Gerhard Nagel; Elisabeth Keim; Dieter Siegele The ASME code cases N-629 and N-631 permit the use of a master curve-based index temperature ( RT To ≡ T 0 + 19.4 ° C ) as an alternative to traditional RT NDT -based methods of positioning the ASME K IC and K IR curves. This approach...
