High‐Entropy Alloy Design Toward Cobalt Substitution for High Hardness and Low Wear Rate Using X–Cr–Fe–Mn–Ni System

Advanced Engineering Materials, EarlyView.
This study explores the replacement of cobalt using the high‐entropy alloy design strategy for wear‐resistant components operating at high temperatures. Starting from the Cantor alloy, cobalt is substituted with Cu, Al, V, or Mo. Metallurgical and tribological analyses reveal that aluminum, vanadium, and molybdenum effectively strengthen the developed ...

Enhancing Fatigue Performance by Tuning of Residual Stresses in Welded Joints through Nanometallic Multilayer

Advanced Engineering Materials, EarlyView.
This study investigates the fundamental mechanisms of a novel postweld treatment that significantly enhances fatigue performance through engineered residual stress (RS) states. A multiscale approach correlates tensile RS in the nanometallic multilayer coating with corresponding compressive RS in the steel substrate, thereby reducing localized stress ...

Efficient and Scalable Radiative Cooling for Photovoltaics Using Solution‐Processable and Solar‐Transparent Mesoporous Nanoparticles

Advanced Functional Materials, EarlyView.
Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...
