Thermal stability of microstructure, mechanical properties, formability parameters and crystallographic texture in an Al-7075 alloy processed by accumulative roll bonding

open access: yesJournal of Materials Research and Technology, 2021
Accumulative roll bonding (ARB) is a severe plastic deformation (SPD) technique that has been extensively used in a wide range of metals to improve their mechanical properties.

On the correlation of shear band formation and texture evolution in $\alpha$-brass during accumulative roll bonding

open access: yes, 2018
We studied the microstructural evolution of the low stacking fault energy $\alpha$-brass alloy CuZn15 during accumulative roll bonding (ARB). Most notably, the typical brass-type texture was clearly observed after four ARB passes (approx.

Investigation on shakedown response-behavior of thawed subgrade soils under long-term traffic loading

open access: yesFrontiers in Earth Science
The shakedown state of the subgrade is crucial for the sustainable design and long-term stability evaluation of pavement structures. In order to characterize the plastic deformation and shakedown behavior of subgrade soil in seasonal frozen regions ...

Depth-sensing thermal stability of accumulative fold-forged nanostructured materials

open access: yesMaterials & Design, 2021
Accumulative fold-forging (AFF) as a newly developed severe plastic deformation (SPD) process based on the repetitive fold-forging steps is implemented for the production of the layered UFG (~200 nm) AA8006 alloy and AA8006-B4C nanocomposite (~35 nm, 10 ...

Study of the microstructure, tensile properties and hardness of AZ61 magnesium alloy subjected to severe plastic deformation [PDF]

open access: yes, 2018
Hot extruded (EX) AZ61 magnesium alloy was processed by the twist channel angular pressing (TCAP) method, which combines equal channel angular pressing (ECAP) and twist extrusion (TE) processes and significantly improves the efficiency of the grain ...

Laboratory Model Tests of Seismic Strain Response of Anti-Seismic Anchor Cables

open access: yesFrontiers in Earth Science, 2022
Under the impact of seismic forces, the strain of conventional anchor cables tended to increase sharply in an instant, which could easily cause the anchor cables to fail due to stress overload.

A probabilistic study on seismic induced accumulated plastic strain

open access: yes, 2023
A linearization method based on the work of Nguyen [Analyse systématique du concept de comportement linéaire équivalent en ingénierie sismique, PhD., université Paris-Est; EDF; ESTP, Cachan (2017)] is extended in this paper. The method is based on the fitting of the relative acceleration transfer function of a linear SDOF oscillator on non-linear ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Formation mechanism of continuous gas leakage paths in cement sheath during hydraulic fracturing

open access: yesEnergy Science & Engineering, 2020
Continuous gas leakage paths of cement sheath during hydraulic fracturing were investigated in this study. The finite‐element models of a casing–cement‐sheath–formation assembly for the whole wellbore were established, the integrity of the cement sheath ...
