Modulating Hierarchical Microstructure to Enhance Strength–Ductility Synergy in an Additively Manufactured Zinc‐Magnesium Alloy via Static Magnetic Field

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Additive manufacturing of zinc‐magnesium (Zn‐Mg) alloys via laser powder bed fusion (LPBF) has gained significant recognition as a promising candidate for bone repair. However, the presence of coarse yet brittle eutectic phases in the fabricated Zn‐Mg alloys tends to induce premature stress concentration and resultant fracture during ...

Chromate‐Conversion‐Induced Cr2O3‐Rich Interphase for Dendrite‐Free and Highly Reversible Zinc Metal Anodes

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Aqueous zinc batteries hold great promise for large‐scale energy storage, yet their practical application is hindered by dendrite growth and interfacial side reactions on the zinc anode. Inspired by the industrially mature chromate passivation technology, this work reports an in situ construction of a chromium‐rich passivation layer (Zn@Cr) on

Unveiling Entropy‐Driven Hard‐Tough Synergy Mechanisms in High‐Entropy Carbonitride Ceramics

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT High‐entropy ceramics manifested promise for extreme environments, yet their phase stability and mechanical synergy mechanisms remain elusive. Herein, entropy‐difference carbonitrides, including (TaTiV)CN, (TaTiVNb)CN, and (TaTiVNbHf)CN, were designed and consolidated via spark plasma sintering.

Strength–Ductility Enhancement in Additively Manufactured Titanium Alloys via Neutral Element‐Mediated Microstructural Control

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT To overcome the challenges of the strength‐ductility trade‐off in laser additively manufactured (LAM) titanium alloys, and to avoid the intragranular microstructure degradation often caused by an exclusive focus on grain equiaxialization, this work proposes a novel strategy of “grain morphology‐intragranular microstructure co‐optimization ...

Dual‐Layer Solid Electrolyte Interphase Enables Effective Suppression of Lithium Dendrites

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The heterogeneous solid electrolyte interphase (SEI) at the Li metal anode often leads to slow and uneven Li+ flux, causing severe Li dendrite growth. Herein, we combine X‐ray photoelectron spectroscopy and cryogenic transmission electron microscopy to demonstrate that a dual‐layer SEI, consisting of an inorganic inner layer and an organic ...

诱导结晶技术处理低浓度含氟废水的试验研究

Gongye shui chuli
针对低浓度含氟废水处理稳定达标与资源化回收的问题，建立了以碳基磷灰石为晶种诱导氟磷酸钙结晶工艺。系统探讨了投加方式对除氟效果的影响，并评估了长期流化床运行结晶产物的资源回收可行性。结果表明，在投加45 g/L碳基磷灰石晶种、钙磷氟物质的量比为12：4.5：1的条件下，可稳定将流化床中氟浓度为20 mg/L的含氟废水降至1.5 mg/L以下。通过合理控制加碱方式以维持晶种活性，流化床运行210 h内可保持高效除氟，诱导结晶效果显著，工艺运营成本为4.78元/t。晶体产物呈包覆型结晶，粒径显著增大 ...

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

Rare 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
