Mechanical properties, microstructure, and texture evolution of copper sheets subjected to differential speed rolling process

Materials Research Express, 2022
Copper sheets were subjected to differential speed rolling (DSR) at roll speed ratios (RSRs) from 1 to 3. The effects of the RSR on the yield strength, uniform strain, microstructure, and texture evolution in the copper sheets were investigated.

Three-dimensional maps of geometrically necessary dislocation densities in additively manufactured Ni-based superalloy IN718

International Journal of Plasticity, 2020
Abstract In this work, we present a method to characterize the subgranular three-dimensional distribution of geometrically necessary dislocations (GNDs) and apply it to an additively manufactured (AM) Ni-based superalloy IN718. A three-dimensional (3D) Electron Backscatter Diffraction (EBSD) data set was obtained using TriBeam tomography with ...

Synergistic strengthening driven by boundary-dislocation architectures in hot-rolled NiV7 alloy

Journal of Materials Research and Technology
Single-phase NiV7 alloy plates were hot-rolled at 900 °C, 1050 °C and 1200 °C, respectively. Electron-backscatter diffraction (EBSD) analyses reveal that elevating the rolling temperature enlarges the average grain size from 18.2 μm to 32.5 μm and ...

Gradient‐Conductivity Architecture Enables Synchronous Enhancement of Sensitivity and Detection Range in Multifunctional All‐Paper Sensors

Advanced Functional Materials, EarlyView.
A gradient‐engineered all‐paper sensor is fabricated by integrating MXene and in situ grown AgNPs within hierarchical cellulose networks. The device breaks the sensitivity–detection range trade‐off through cascaded conductive pathways, enabling ultrahigh pressure sensitivity, humidity–pressure decoupled dual‐mode sensing, and outstanding EMI shielding,

Unified Phase‐Field Framework for Antiferroelectric, Ferroelectric and Dielectric Phases: Application to HZO Thin Films

Advanced Functional Materials, EarlyView.
HfxZr1−xO2${\rm Hf}_x{\rm Zr}_{1-x}{\rm O}_2$ offers CMOS‐compatible nanoscale ferroelectricity yet suffers from a high Ec${\rm E}_c$ demanding large operating voltages. A unified phase‐field framework spanning AFE/FE/DE phases shows how FE grains soften neighboring AFE grains over λ$\lambda$ ≈$\approx$ 22–37 nm.
