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 ScienceTemper 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–

Determination of ductile-to-brittle transition temperature of NIOMOL 490K steel welded joints [PDF]
Procedia Structural Integrity, 2022 This paper is devoted to the ductile-brittle transition behavior of high strength low alloyed structural steel NIOMOL 490K. This steel grade is designed for welded pressure vessels exposed to dynamic loads, operating at temperatures below zero, and that is why it must have acceptable toughness.

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 ...

Temperature-induced ductile-to-brittle transition of bulk metallic glasses [PDF]
Applied Physics Letters, 2013 Uniaxial tensile and uniaxial compressive tests for Zr-based bulk metallic glasses (BMGs) were conducted at room and cryogenic temperatures, respectively. It was observed that both the change of macroscopic fracture mode from ductile shear fracture to brittle normal tensile fracture and microscopic fracture feature from micron-scaled vein patterns to ...
