Nitride‐Reinforced Metal Matrix Nanocomposite Powders Production by Plasma‐Assisted Thermochemical Treatment of Intermetallic Powders

open access: yesAdvanced Engineering Materials, Volume 28, Issue 5, 4 March 2026.
This study proposes a new methodology for producing metal matrix nanocomposites in the solid state. The process involves the plasma‐assisted thermochemical treatment of metallic alloy powders. As a proof‐of‐concept, TiN nanoparticles are synthesized directly on the surface of FeTi intermetallic powder particles, enabling the development of the ...

Single‐Pulse Nanomorphology Governs Laser‐Induced Periodic Surface Structure Formation on Metals

open access: yesLaser &Photonics Reviews, Volume 20, Issue 2, 22 January 2026.
Ultrashort pulse ablation enables generation of self‐organized periodic structures, where evolving nanomorphology controls pulse‐to‐pulse feedback. In noble metals, nanospikes form after the first pulse and localize surface waves, preventing periodic field distributions and thus suppressing their formation.

Direct Recycling of Cold Work Tool Steel Swarf into New Cutting Disks via Field‐Assisted Sintering

open access: yesAdvanced Engineering Materials, Volume 27, Issue 22, November 2025.
Through a sintering method known as field‐assisted sintering technology/spark plasma sintering, cold work tool steel swarf can be directly recycled into new cutting disks. This method is capable of densifying the unconventional powder morphology of swarf, and it can also seal grinding contaminants, such as Al2O3, into the steel matrix.
