Constraining the long-term evolution of the slip rate for a major extensional fault system in the central Aegean, Greece, using thermochronology [PDF]

, 2006
The brittle/ductile transition is a major rheologic boundary in the crust yet little is known about how or if rates of tectonic processes are influenced by this boundary.

The brittle–ductile transition in single-crystal iron [PDF]

Acta Materialia, 2008
Abstract The fracture behaviour of single-crystal pure iron was studied by four-point bending of pre-cracked specimens at temperatures between 77 and 180 K and strain rates between 4.46 × 10−5 and 4.46 × 10−3 s−1. Fracture behaviour changes from brittle to ductile with increasing temperature. The brittle–ductile transition (BDT) temperature increases

Brittle–ductile transitions in vanadium and iron–chromium [PDF]

Journal of Nuclear Materials, 2007
Abstract We report ongoing experimental work on fracture and brittle–ductile transitions in vanadium, iron and iron–9% chromium single crystals and polycrystals. Tests were carried out by four-point bending of pre-cracked specimens in the temperature range 77–300 K, at a variety of strain rates.

Effect of the viscosity ratio on the PLA/PA10.10 bioblends morphology and mechanical properties [PDF]

, 2018
PLA bio-blends with a predominantly biosourced PA10.10 in the composition range 10-50wt.% were prepared by melt blending in order to overcome the advanced brittleness of PLA.

Critical Depth of Hard Brittle Materials on Nano Plastic Forming

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2008
This paper reports on ductile to brittle transition of hard brittle materials in nano plastic forming process. Formability of some hard brittle materials, i.e., glasses, silicon and quartz wafers, were examined through a specially designed and developed ...

Study on impact properties of Ti6211 titanium alloy at different temperatures [PDF]

MATEC Web of Conferences, 2020
In this paper, Charpy notched pendulum test was used to study the impact properties of Ti6211 titanium alloy at -60 ℃, -40 ℃, -20 ℃, 23 ℃, 100 ℃, 200 ℃ and 300 ℃, respectively, and the fracture morphology was analyzed.

Deep ductile shear localization facilitates near-orthogonal strike-slip faulting in a thin brittle lithosphere [PDF]

, 2020
Some active fault systems comprise near-orthogonal conjugate strike-slip faults, as highlighted by the 2019 Ridgecrest and the 2012 Indian Ocean earthquake sequences.

Brittle–ductile transitions in polycrystalline tungsten

Philosophical Magazine, 2010
The strain rate dependence of the brittle-to-ductile transition (BDT) temperature was investigated in notched and un-notched miniature bars made of high-purity polycrystalline tungsten and in notched bars of less-pure sintered material. The activation energy, E BDT, for the process controlling the BDT in pure tungsten was equal to 1.0 eV both in un ...

Brittle-ductile coupling : Role of ductile viscosity on brittle fracturing [PDF]

, 2005
International audienceLocalized or distributed deformations in continental lithosphere are supposed to be triggered by rheological contrasts, and particularly by brittle-ductile coupling.

Burial depth interval of the shale brittle–ductile transition zone and its implications in shale gas exploration and production

Petroleum Science, 2017
Brittleness and ductility of shale are closely related to shale gas exploration and production. How to predict brittleness and ductility of shale is one of the key issues in the study of shale gas preservation and hydraulic fracturing treatments.
