Evaluation of DBTT and Creep Properties of Aged Main Valve Casing by Using Small Punch Specimens
Key Engineering Materials, 2005Both the change in DBTT and the degradation of creep properties of the aged CrMoV cast steel which had been actually used as a main steam valve were evaluated from the conventional SP test and the SP creep (SP-C) test using by SP test specimens. The CVN DBTTs of the virgin and aged steels were estimated to be 280 and 369 K by the conventional SP test ...

Abstract The small punch (SP) test technique using TEM disk miniaturized specimens has been developed to evaluate the ductile-brittle transition temperature (DBTT) for irradiated ferritic structural steels. The SP tests were performed for F-82 (8Cr-2W-V), F-82H with Ta and HT-9 (12Cr-lMo-V-W) ferritic steels under consideration for demonstrating a ...

Integrity of structures in various technologies depend on the fracture behaviors of materials, and in general the fracture characteristics of s tructural m aterials are evaluated using destructive tests, such as Charpy, fracture toughness, and other such techniques.

Modelling of the Charpy Impact Test in the DBTT Range
Materials Science Forum, 2005The finite element method was used in order to compute the energy balance and the stress-strain distribution in the Charpy V-notch specimen. Inertial effects were taken into account by a fully dynamic computation. It was shown that inertial oscillations are damped by viscoplasticity ahead the notch and vanish rapidly. 3D modelling is needed since large

Effect of Initial Heat Treatment on DBTT of F82H Steel Irradiated by Neutrons
Fusion Science & Technology, 2005The dependence of ductile-brittle transition temperature (DBTT) on tempering time and temperature was examined for a martensitic steel F82H irradiated at 150 and 250°C to a neutron dose of 1.9 dpa ...
