...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...

..., 2013. Assoc. Editor: David L. Rudland. 23 01 2013 25 06 2013 The Master Curve gives the relation between the median of fracture toughness of ferritic steels and the temperature in the ductile–brittle transition temperature region. The procedure used to determine the Master Curve...

... specimen J Ic K Jc master curve precracked Charpy T 0 In 1965, the U.S. Atomic Energy Commission (USAEC), at the advice of the Advisory Committee on Reactor Safeguards (ACRS), initiated the process that resulted in the establishment of the Heavy Section Steel Technology (HSST) program...

...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...
