Impact toughness scattering of bainitic steel in the ductile-brittle transition temperature region

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2016
The impact toughness scattering in the ductile-brittle transition temperature (DBTT) region was experimentally examined on mixed and homogeneous grains of low alloy high strength bainitic steel under dynamic loading conditions. The results revealed that the mixed grain microstructure had larger impact toughness scattering than the homogeneous one, and ...

Specimen size effects on ductile–brittle transition temperature in Charpy impact testing

Journal of Nuclear Materials, 2004
Abstract One key issue for small specimen test techniques is to clarify specimen size effects on test results. In consideration of size effects on determining the ductile-to-brittle transition temperature (DBTT) in Charpy impact testing, a method to evaluate the plastic constraint loss for differently sized Charpy V-notch (CVN) specimens is proposed ...

The nature of the failure of poly crystalline molybdenum in the temperature range of the ductile-brittle transition

Strength of Materials, 1975
The effects of C on failure of polycrystalline Mo under uniaxial tension in the ductile-brittle transition temperature range were investigated. It was found that in a two-phase molybdenum alloy of optimal composition the structural states of the boundary zones and the matrix are qualitatively equivalent to one another: on loading the deformation is ...

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 ...
