Rheological transitions in the middle crust: insights from Cordilleran metamorphic core complexes [PDF]

Solid Earth, 2017
High-strain mylonitic rocks in Cordilleran metamorphic core complexes reflect ductile deformation in the middle crust, but in many examples it is unclear how these mylonites relate to the brittle detachments that overlie them.

Aging‐Induced Ductile‐Brittle‐Ductile Transition in High‐Entropy Alloys and its Implications [PDF]

Advanced Science
Temper embrittlement, characterized by a dramatic loss of ductility within a narrow temperature window, is ubiquitous in conventional alloys but is not reported in compositionally complex or high‐entropy alloy systems. Here, an unexpected ductile–brittle–

Polyolefin ductile-brittle transition temperature predictions by machine learning

Frontiers in Materials
Polymers show a transition from ductile-to brittle fracture behavior at decreasing temperatures. Consequently, the material toughness has to be determined across wide temperature ranges in order to determine the Ductile-Brittle Transition Temperature ...

A Study on the Brittle-to-Ductile Transition Temperature of Forged β-Solidifying TiAlMn and TNM Alloys

Crystals, 2022
To further determine the brittle-to-ductile transition temperature, the microstructures and mechanical properties of typical forged β-solidifying Ti-42Al-5Mn (TiAlMn) and Ti-43Al-4Nb-1Mo-0.5B (TNM) alloys were studied.

Constitutive Behavior of Olivine Gouge Across the Brittle‐Ductile Transition

Geophysical Research Letters, 2023
The bottom of the lithosphere is characterized by a thermally controlled transition from brittle to ductile deformation. While the mechanical behavior of rocks firmly within the brittle and ductile regimes is relatively well understood, how the ...

Application of a Tensile Test Method to Identify the Ductile-Brittle Transition of Caramel

Foods, 2022
During cutting of foods, tensile stresses in front of the blade are responsible for the separation of the material. Therefore, tensile tests can be helpful to gain knowledge on deformation properties related to pre-fracture cutting behavior as well as on
