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

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 ...

A Study of Mechanics in Brittle–Ductile Cutting Mode Transition
Micromachines, 2018 This paper presents an investigation of the mechanism of the brittle–ductile cutting mode transition from the perspective of the mechanics. A mechanistic model is proposed to analyze the relationship between undeformed chip thickness, deformation, and ...

Ductile-to-brittle transition in aluminum alloys
Materials Research LettersHere 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 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–

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

Ductile-to-Brittle Transition of Steel Due to Dynamic Loading
MetalsThe transition from ductile to brittle for metals is usually encountered during fast machining operations, in low-temperature environments, and in all situations involving very high strain rates.

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.
