The Microstructure and High‐temperature Cycle Oxidation Mechanism of the Nickel‐Based Superalloy Surface Treated by Laser Shock Processing and Ion Implantation at 1100 °C

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 3, 3 February 2026.
Laser shock processingcombination with Hf ion implantation results in dual modification on the surface of GH202 nickel‐based superalloy, which induces a large number of crystal defects, providing channels for the diffusion of metal cations. Hf ion implantation forms an amorphous HfO2 layer.

Multicomponent Rare‐Earth Monosilicate Reactions With Calcium‐Magnesium Aluminosilicate

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT High‐temperature reactions of multicomponent rare‐earth monosilicates (REMS) with calcium‐magnesium aluminosilicate (CMAS) were investigated at 1300°C for 24 h. Three compositional series were tested, each ranging from 1‐cation to 4‐cation REMS, with cations selected to interrogate compositional effects on CMAS reactivity. The final members of

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, 21 January 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 ...
