Probing the Statistical Validity of the Ductile-to-Brittle Transition in Metallic Nanowires Using GPU Computing

open access: yes, 2013
We perform a large-scale statistical analysis (> 2000 independent simulations) of the elongation and rupture of gold nanowires, probing the validity and scope of the recently proposed ductile-to-brittle transition that occurs with increasing nanowire ...

Evolution of hydrothermal regime along a crustal shear zone, Tinos island, Greece [PDF]

open access: yes, 2004
International audienceStructural, cathodoluminescence and SIMS δ18O analyses of quartz-calcite veins are combined to constrain the evolution in space and time of fluid infiltration in an exhuming detachment shear zone (Tinos Island, Cyclades, Greece ...

Rupture by damage accumulation in rocks [PDF]

open access: yes, 2006
The deformation of rocks is associated with microcracks nucleation and propagation, i.e. damage. The accumulation of damage and its spatial localization lead to the creation of a macroscale discontinuity, so-called "fault" in geological terms, and to the

Crustal Thermal Structure and Exhumation Rates in the Southern Alps Near the Central Alpine Fault, New Zealand

open access: yesGeochemistry, Geophysics, Geosystems, 2020
We investigate orogenic uplift rates and the thermal structure of the crust in the hanging wall of the Alpine Fault, New Zealand, using the hypocenters of 7,719 earthquakes that occurred in the central Southern Alps between late 2008 and early 2017, and ...

Strength models of the terrestrial planets and implications for their lithospheric structure and evolution

open access: yesProgress in Earth and Planetary Science, 2021
Knowledge of lithospheric strength can help to understand the internal structure and evolution of the terrestrial planets, as surface topography and gravity fields are controlled mainly by deformational features within the lithosphere.

The Cold-Brittleness Regularities of Low-Activation Ferritic-Martensitic Steel EK-181

open access: yesMetals, 2023
The behavior of the EK-181 low-activation ferritic-martensitic reactor steel (Fe–12Cr–2W–V–Ta–B) in the states with different levels of strength and plastic properties after traditional heat treatment (THT) and after high-temperature thermomechanical ...

Dispersion-strengthened chromium alloy [PDF]

open access: yes, 1972
Finely divided powder mixture produced by vapor deposition of CR on small ThO2 particles was hot pressed or pressure bonded. Resulting alloy has lower ductile-to-brittle transition temperature than pure chromium, and high strength and oxidation ...

Study on temper embrittlement and hydrogen embrittlement of a hydrogenation reactor by small punch test [PDF]

open access: yes, 2017
The study on temper embrittlement and hydrogen embrittlement of a test block from a 3Cr1Mo1/4V hydrogenation reactor after ten years of service was carried out by small punch test (SPT) at different temperatures.

Intrinsic Mechanisms of Ductile-brittle Transition for F460 Steel Welding Coarse Grained Heat Affected Zones with Different Heat Inputs

open access: yesCailiao gongcheng, 2016
Coarse grain heat affected zone (HAZ) of F460 steel was simulated by a Gleeble 3800 thermo-mechanical simulator. The microstructure, critical event of the HAZ formed at various heat inputs (E) were characterized and determined by optical microscopy (OM ...
