Synergy of Strength and Plasticity in Extruded VZ91K Magnesium Alloy Achieved by Constructing Bimodal Grain Structure via Suppression of PSN‐DRX

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Bimodal grain structure (BGS) demonstrates significant potential in synergistically optimizing the strength and plasticity of magnesium alloys. Acquiring the desired BGS consequently became a critical challenge. This study took the Mg‐9Gd‐1Zn‐0.5Zr (wt%, VZ91K) alloy as its subject. From the perspective of BGS formation mechanisms, it suggests

Thermite‐Synthesized Fe–Ti–Al–Mg High‐Entropy Intermetallic Compound for Efficient Azo Dye Degradation

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Most high‐entropy alloys (HEAs) tailored for contaminant degradation suffer from complex fabrication processes and high‐cost alloy design. Furthermore, low‐cost active elements such as Fe and Mg cannot be readily alloyed into HEAs via conventional routes.

SE PUBLICAR É PRECISO, AVALIAR TAMBÉM É! [PDF]

open access: yesRevista de Administração de Empresas, 2018
O tema “revisão de artigos” é relevante e faz parte do cotidiano de todo pesquisador. Entretanto, a minha experiência como editor e revisor em periódicos brasileiros e internacionais torna evidente que o comprometimento dos pesquisadores na função de revisores, em geral, é muito menor do que quando estão na posição de autores.

Achieving Superior Strength‐Ductility Synergy in Bionic Magnesium‐Iron Composites by Topological Optimization

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Magnesium (Mg)‐based composites are regarded as promising lightweight materials with significant potential for structural applications. The structure–property relationships of bionic Mg‐based composites remain unclear. Herein, three honeycomb‐like Mg‐Fe composites are fabricated to uncover the underlying strengthening mechanisms.
