Determination of the minimum quantity of irradiated ferritic steel specimens for small punch DBTT testing

Journal of Nuclear Materials, 1991
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 ...

Evaluation of ductile–brittle transition temperature (DBTT) of aluminide bond coats by micro-tensile test method

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2010
A method has been suggested to accurately determine the DBTT of diffusion aluminide bond coats. Micro-tensile testing of free-standing coating samples has been carried out. The DBTT was determined based on the variation of plastic strain-to-fracture with temperature.

Indentation-energy-to-fracture (IEF) parameter for characterization of DBTT in carbon steels using nondestructive automated ball indentation (ABI) technique

Scripta Materialia, 1998
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.

Determination of DBTT of functionally graded steels using Artificial Intelligence

2023
This study applied three Artificial Intelligence (AI) models to project the ductile to the brittle transition temperature (DBTT) of functionally graded steels (FGS). These prediction models are Minimax Probability Machine Regression (MPMR) model, Genetic Programming (GP), and Emotional Neural Network (ENN) algorithms with strong prediction performance.

Modelling of the Charpy Impact Test in the DBTT Range

Materials Science Forum, 2005
The 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, 2005
The 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 ...
