Ductile and brittle transition behavior of titanium alloys in ultra-precision machining [PDF]

Scientific Reports, 2018
Titanium alloys are extensively applied in biomedical industries due to their excellent material properties. However, they are recognized as difficult to cut materials due to their low thermal conductivity, which induces a complexity to their deformation

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–

Effects of temperature on fatigue crack growth rates of a low-carbon pipe steel in the ductile and ductile-to-brittle transition regions

Journal of Pipeline Science and Engineering, 2023
This study investigated the impact of temperature on Fatigue Crack Growth Rates (FCGR) of low-carbon pipe steel in both the ductile and ductile-to-brittle transition regions.

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 ...

Brittle-ductile transition stress of different rock types and its relationship with uniaxial compressive strength and Hoek–Brown material constant (m i )

Scientific Reports, 2023
Rocks deformed at low confining pressure are brittle, which means that after peak stress, the strength declines to a residual value established by sliding friction. The stress drop is the variation between peak and residual values.

Theoretical modelling of brittle-to-ductile transition load of KDP crystals on (001) plane during nanoindentation and nanoscratch tests

Journal of Materials Research and Technology, 2020
KDP single crystals are widely used in inertial confinement fusion and high power lasers due to the wide transmission band, high laser damage threshold, large nonlinear optical coefficient, etc.

The brittle-ductile transition in active volcanoes [PDF]

Scientific Reports, 2019
AbstractContrasting deformation mechanisms precede volcanic eruptions and control precursory signals. Density increase and high uplifts consistent with magma intrusion and pressurization are in contrast with dilatant responses and reduced surface uplifts observed before eruptions.

Micro- versus macro- modelling of creep damage [PDF]

Computer Methods in Materials Science, 2009
In the present paper the continuous approach to model brittle-ductile transition in creep failure phenomenon is replaced by Cellular Automata (CA) model. This allows to back-up this complex phenomenon by relating it to microstructural changes.
