Oxophilic Yb2O3 nanoparticles as radical scavengers to enhance the durability of Fe–N–C oxygen reduction catalysts

open access: yesSmart Molecules, EarlyView.
Fe–N–C catalysts suffer from radical attack during oxygen reduction. By immobilizing oxophilic Yb2O3 nanoparticles near Fe–N4 sites as efficient radical scavengers, the catalyst achieves enhanced activity and stability. Abstract The practical application of Fe–N–C catalysts in proton exchange membrane fuel cells is substantially limited by their ...

HWTS 50 Tool Steel Tailored for Laser Powder Bed Fusion: Sliding Wear of Bare Surfaces and Nitriding Response in Comparison with 18Ni300 and AISI H13

open access: yessteel research international, EarlyView.
This work investigates the wear resistance and nitriding behavior of PBF‐LB/M‐processed Osprey HWTS 50, a lean hot work tool steel. Three heat treatment conditions are compared to conventional wrought H13, H11, and PBF‐LB/M 18Ni300. The study highlights HWTS 50's enhanced nitrogen diffusion, deeper nitriding hardness depth, and comparable or improved ...

Tailored Hardening and Isothermal Bainitizing of Additively Manufactured Nitrogen‐Enhanced Martensitic Chromium Steel

open access: yessteel research international, EarlyView.
Tailored heat treatments transform additively manufactured high‐nitrogen martensitic Cr steel from austenitic as‐built condition to high‐hardness states. Isothermal bainitizing at 250°C generates an ultrafine nanostructure and achieves higher hardness than conventional hardening and tempering, highlighting a promising postprocessing route for laser ...
