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

open access: yesAdvanced Engineering Materials, Volume 28, Issue 2, January 21, 2026.
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 ...

Inverted-T-shaped YBaCuO bulks improving high-temperature superconducting maglev performance

open access: yesJournal of Highway and Transportation Research and Development
The high-temperature superconducting (HTS) maglev system uses the self-stabilizing force for the synchronous levitation and guidance. This unique passive-stable levitation is generated by the induced current of HTS bulks in a gradient magnetic field. The
