Grain size dependence of twin nucleation in magnesium alloys

Journal of Materials Research and Technology
Twinning plays a prominent role in the plastic deformation of low-symmetry crystals such as magnesium alloys. However, the capture of twin nucleation has been challenging since the process is rapid and difficult to predict, making it impossible to ...

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 ...

Torsional strain-induced microstructural control in magnesium alloys: A pathway to enhanced mechanical performance

Materials & Design
To achieve a strength-ductility synergy in extruded ZM6 magnesium alloy, three torsion-dominated heterogeneous plastic deformation processes were proposed. The deformation mechanisms and the evolution of microstructure, texture, twin volume fraction (TVF)

Electron-induced evolution of dislocation density and morphology in Mg-Y-Nd-Gd-Zr alloy at ultra-low temperature

Journal of Magnesium and Alloys
This study elucidates the non-thermal mechanism of dislocation density reduction in a Mg-Y-Nd-Gd-Zr alloy under continuous electropulsing (6.67–15 A/mm²) at ultra-low temperatures (−150 °C to −196 °C) through tripartite characterization and first ...
