Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Pyritum can eliminate blood stasis and promote the healing of muscles and bones, which has been used as a traditional mineral medicine in China for thousands of years. However, the mechanisms of action and processing methods of Pyritum were not illustrated.

Rare 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 ...

Rare 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 ...

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

Shuitu Baochi Xuebao, 2018 为探究煤矸石对盐碱土壤绿化的改良效果和对土壤微生物的影响，将不同用量（0，10%，20%，30%，40%，50%）和不同粒径（小粒径5 mm，以及小中大粒径等比例的混合粒径）煤矸石施用于盐碱土壤，进行紫花苜蓿盆栽试验，测定紫花苜蓿株高、生物量以及土壤微生物量和酶活性指标。结果表明，不同粒径煤矸石处理的土壤微生物量碳氮，土壤的脲酶、过氧化氢酶、脱氢酶活性，以及紫花苜蓿株高、生物量均随着煤矸石用量的增加呈先增大后降低的趋势，混合粒径、小粒径、中粒径、大粒径煤矸石处理的盐碱土上述指标分别在20%，20%，30%

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.

Rare 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 ...
