Effect of Surface Nanocrystallization on Corrosion Resistance of the Conformed Cu-0.4%Mg Alloy in NaCl Solution

Metals, 2018
Surface nano-crystallization (SNC) of a conform-extruded Cu-0.4 wt.% Mg alloy was successfully conducted by high-speed rotating wire-brushing to obtain the deformed zone with dislocation cells and nanocrystallines. SNC promotes the anodic dissolution and

The tribological behavior of a surface-nanocrystallized magnesium alloy AZ31 sheet after ultrasonic shot peening treatment

Journal of Magnesium and Alloys, 2021
A magnesium alloy AZ31 sheet was processed by ultrasonic shot peening treatment to fabricate a surface nanocrystalline, and a ball-on-disk dry sliding wear test was performed to evaluate the tribological behavior after treatment.

Viscosity of Trachytic Melt Constrained by Integrated Rheological and In Situ Spectroscopic Analyses: Insights From the Agnano‐Monte Spina Eruption (Campi Flegrei, Italy)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Quantifying the viscosity of hydrous volcanic melts is essential for understanding ascent dynamics, degassing efficiency, and fragmentation, yet laboratory measurements may be compromised by syn‐analytical evolution in melt structure at the nanoscale, thus yielding viscosity values not representative of a homogeneous melt phase.

Rare‐Earth‐Induced Fluoride‐Rich Local Structures Governing BaF2 Nanocrystallization in Oxyfluoride Glasses

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
This figure schematically illustrates the formation of BaF2‐like precursor structures in BaF2–ZnO–B2O3 oxyfluoride glass. Rare‐earth ions attract surrounding fluoride ions due to their higher field strength, leading to the formation of fluorine‐rich local environments.

Influence of high-energy shot peening on the microstructure and mechanical properties of Ti–6Al–4V welded joints

Materials Research Express, 2020
In this study, Ti–6Al–4V welded joints were subjected to a high-energy shot peening (HESP) treatment. The structural characteristics of the Ti–6Al–4V welded joints were investigated by optical microscopy (OM) and x-ray diffraction (XRD).

Effect of Worm‐Like Amorphous Phase on Corrosion Resistance and Antibacterial Properties of NiTiCu Alloy

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT By adding CuO, the worm‐like amorphous phase and atomic clusters were simultaneously introduced, enabling the (Ni40Ti40Cu20)99.9O0.1 alloy micron columns to exhibit a uniform flow strain of over 40% and a strength of over 2.5 GPa during compression.

Achieving Ambient‐Temperature Fast Hydrogenation Properties in Ga‐Doped Mg–Ni Alloy: Dual‐Phase Synergistic Catalysis and Stacking Fault Channels

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT The high operating temperatures and sluggish kinetics of Mg‐based hydrogen storage materials (HSMs) are urgently being addressed. In this work, a novel Mg–Ni–Ga HSM with dual‐phase synergistic catalysis is developed, including the fishbone‐like Mg3Ni2Ga1 catalytic phase and the Mg2Ni phase with stacking faults (SFs).
