Electropulsing-driven rapid reversible phase transformations in Al-Mg-Si-Cu alloys

Le Zong, Conghan Huang, Haoyu Huang, Cheng Chen et autres

The electrical free-energy term, ΔGe, has been widely used to rationalize electropulsing-driven ultrafast precipitation and homogenization in age-hardenable alloys. However, its quantitative contribution relative to enhanced kinetics to phase transformation remains unclear. Here, we demonstrate reversible phase transformations in Al-Mg-Si-Cu alloys controlled …

Effect of Rotational Speed on Microstructure Evolution and Mechanical Properties of Zero‐Tilt Friction Stir Welded Mg‐7.8Gd‐4.59Y‐0.92Zn‐0.46Zr Alloy

Yue Wang, Chunjie Xu, Dong Ma, Yu Wen et autres

In friction stir welding (FSW) of high‐strength Mg‐RE alloys, welding‐induced thermo‐mechanical conditions strongly affect weld formation and microstructural evolution. Under a zero‐tilt configuration, altered material flow and consolidation behavior make tool rotational speed particularly important. This study investigates the effect of rotational …

Magnetically Boosted Water‐Splitting Performance in Metallic Glasses

Chaoqun Pei, Zheng‐Jie Chen, Yuyang Qian, Zhichao Lu et autres

ABSTRACT Developing high‐performance non‐precious metal electrocatalysts for hydrogen production is vital to combat the energy crisis. Metallic glasses (MGs), a promising class of novel materials, have emerged as a focal point in the search for efficient catalysts. However, the lack of long‐range …

Exceptional magnetic shielding via ultra-low-remanence co-based amorphous alloys engineered by atomic ordering

Yuyang Qian, Chaoqun Pei, Congrui Yang, Zida Zhang et autres

Ubiquitous electromagnetic signals enable modern information exchange but also cause radiation, interference, and data security risks. Shielding low-frequency magnetic fields (f < 100 kHz) remains challenging because conventional materials exhibit high residual magnetization that weakens shielding performance. Here, ultra-low residual magnetization in …

The global burden of hearing loss and its comorbidity with chronic diseases: a comprehensive analysis from 1990 to 2021

Yubin Xue, Dong Ma, Yaqian Zhang, Chao Fang Dong et autres

Age-related hearing loss (HL) is an increasing contributor to the global burden of disease in aging populations. Its interactions with major chronic diseases remain insufficiently characterized. We analyzed data from the Global Burden of Disease 2021 study for adults aged ≥ 45 …
