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

Investigation of an Updated Continuum Damage Model in the DBTT Region

AIP Conference Proceedings, 2010
With the investigation of influence of the stress triaxiality on the fracture properties, an updated continuum damage model is proposed and realized by FEA to evaluate the temperature effect and the strain rate effect on the fracture properties in the ductile and brittle transition temperature (DBTT) region.

Determination of Ductile-Brittle Transition Temperature (DBTT) in Dynamic Small Punch Test

Journal of Testing and Evaluation, 1992
Abstract A dynamic small punch test technique is demonstrated for measuring the ductile-brittle transition temperature (DBTT) of aged Cr-Mo-V turbine rotor steels. Based on fracture energy measurements and fracture surface observations it is shown that the dynamic small punch test specimens exhibit a clear ductile-brittle transition ...
