Overcoming Thermodynamic and Kinetic Constraints of Recrystallization and Precipitation in Cu‐Ni‐Sn Alloy via Electropulsing Treatment

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT The performance optimization of ultrahigh‐strength Cu‐15Ni‐8Sn alloy relies on controlling recrystallization and aging precipitation, which are two thermally activated processes constrained by high activation barriers. Conventional heat treatment requires elevated temperatures and prolonged holding time, inevitably leading to grain coarsening ...

单颗粒液滴飞溅对颗粒起动的影响

open access: yesShuitu Baochi Xuebao, 2022
通过室内模拟降雨试验,探究单颗粒液滴飞溅对泥沙颗粒起动的影响。试验共设计4种地表坡度(0,15°,25°,35°)及4种粒径的均匀沙(0.098~0.104,0.104~0.5,0.5~0.78,1~1.4 mm),选取当量直径为4.5 mm的液滴进行模拟试验,同时利用高吸水树脂材料泡发后的水球作为对照组。结果表明,颗粒直径和坡度的变化对颗粒起动的影响较为显著,飞溅子液滴对液滴溅蚀具有重要意义。随着颗粒直径的增大,颗粒的起动逐渐由液滴冲击和子液滴飞溅裹挟共同作用转变为液滴冲击动能传递为主,飞溅携带为辅 ...

Predictive M‐Site Design of MAX‐Derived CoNi Composites: Dual‐Scale TaC + L12 Strengthening Enabled by Rare Metal Ta

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT In MAX‐phase‐derived metal–matrix composites, the M‐site element simultaneously governs carbide chemistry and matrix precipitate stability, yet it has traditionally been selected empirically rather than from a predictive criterion linking M‐site choice to carbide chemistry, matrix alloying, and L12 stability; moreover, the reaction pathway ...

不同粒径厌氧氨氧化颗粒污泥的性状研究

open access: yesGongye shui chuli, 2014
通过实验比较了不同粒径Anammox颗粒污泥的物理性质和处理效果的差异。实验结果表明,Anammox颗粒污泥粒径的增大有助于减小颗粒污泥受到的不利条件的影响;粒径为0.5~1.0、1.0~1.5 mm及1.5 mm以上3组Anammox颗粒污泥的比反应速率(以N计)分别为0.52、0.62 、0.55 g/(g·d)。综合考虑去除效果及稳定性,在本实验系统中,粒径在1.0~1.5 mm的Anammox颗粒污泥的综合性能最佳。

Time‐Efficient Columnar‐to‐Equiaxed Transition via High Magnetic Field Processing

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT The need to simplify processing routes and improve processing efficiency motivates the development of time‐efficient methods for inducing the columnar‐to‐equiaxed transition (CET) during solidification while tailoring material performance. Conventional multistep CET approaches are time‐consuming and often struggle to simultaneously regulate ...

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

open access: yesRare 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.

Ultrasound‐Driven Dual Piezocatalytic–Electrical Scaffold Synergistically Promotes Osteoporotic Bone Healing

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The regeneration of osteoporotic bone defects is severely hampered by compromised endogenous healing capacity, demanding advanced strategies that actively orchestrate pro‐osteogenic microenvironments. Here, we report an integrated, self‐powered osteo‐regenerative system that uniquely leverages a dual ultrasound‐responsive piezoelectric ...

Insights Into the Temperature‐Dependent Oxidation Mechanism of Metallic Cerium in H2O‐N2 Atmospheres

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Metallic cerium (Ce), a widely used surrogate for actinide metals, enables mechanistic studies of reactions in complex gas environments under controlled and safer laboratory conditions. Here, the oxidation behavior of Ce in H2O‐N2 mixed atmospheres was investigated from 200°C to 350°C using in situ thermogravimetry–mass spectrometry, in situ X‐
