Thermally Induced Creep and Viscoelastic Behavior of Copper Micropillar Arrays

Advanced Science, Volume 13, Issue 22, 17 April 2026.
Copper micropillar arrays are fabricated by electrodeposition within through‐glass‐via, and their thermally induced time‐dependent deformation is quantified. Nanoindentation creep, EBSD, and TEM reveal a heat‐treatment‐driven transition between grain‐boundary‐mediated deformation and dislocation‐dominated creep, while Kelvin modeling captures ...

Tailoring Differentiated Multiscale Microstructure to Enhance the Mechanical Properties of Additively Manufactured AlCoFeNi2 at Room and High Temperatures via Annealing

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Additively manufactured AlCoFeNi series eutectic high‐entropy alloys (EHEAs) exhibit nonequilibrium dual‐phase microstructure in the as‐printed state, allowing them to be easily tailored through annealing to explore their strength–toughness potential.

Crack tip strain evolution and crack closure during overload of a growing fatigue crack [PDF]

, 2017
It is generally accepted that fatigue crack growth is retarded after an overload, which has been explained either by plasticity-induced crack closure or near-tip residual stress.

Study on the Synergistic Effects and Optimization of Flotation Reagent Blends Under Low Reagent Consumption

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 2, March/April 2026.
ABSTRACT Under low reagent dosage, the flotation performance of diesel as a collector was enhanced, and the synergistic mechanism of diesel blended with oleic acid and CTAB was investigated. Results showed that compared to pure diesel, the oleic acid blended system (Blend A) increased clean coal yield by 81.52% to 92.24%, while the CTAB blended system (
