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 ...

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 [PDF]
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 ...

Analysis Of Ductile-To-Brittle Transition Temperature Of Mild Steel [PDF]
, 2014 The Ductile-to-Brittle Transition Temperature (DBTT) is a phe nomenon that is widely observed in metals. Below critical temperature (DBTT),the material suddenly loss ductil ity and becomes brittle. The controlling mechanism of this transition still remains unclear despite of la rge efforts made in experimental and theoretical investigation. All ferrous

Polyolefin ductile-brittle transition temperature predictions by machine learning [PDF]
Frontiers in MaterialsPolymers 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 ...

Proceedings of the National Academy of Sciences of the United States of America, 2021 Significance This work uncovers the mystery of ductile-to-brittle transition (DBT) in body-centered cubic (BCC) metals. Temperature-dependent dislocation mobility and dislocation nucleation have been proposed as the potential factors responsible for the ...

Brittle-to-ductile transition in high temperature pre-stretched polycarbonate [PDF]
, 2022 The brittle-to-ductile transition is investigated in polycarbonate (PC) after different types of thermomechanical treatment. In addition to the stress versus strain curves in uniaxial stretching to fracture of the original, preheated, shape recovered and

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

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.
