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

Ductile-to-brittle transition in aluminum alloys

Materials Research Letters
Here we exploited room (298 K) – and cryogenic (77 K) – temperature mechanical behaviors of binary Al-Mg alloys across a wide range of magnesium concentration (i.e. 2.8–13.1 at.%). We observed ductile-to-brittle transition at 77 K as Mg content increases

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 prestrain on the ductile-to-brittle transition of ice

Acta Materialia, 2016
AbstractThe ductile-to-brittle transition was investigated in prestrained columnar ice at −10 °C. Laboratory-grown specimens of freshwater and saline ice were prestrained under uniaxial across-column compression (to levels from εp = 0.003 to εp = 0.20, at constant strain rates in the ductile regime) and likewise reloaded (at rates from 1 × 10−6s−1 to 3

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.
