Additive Manufacturing of Hot Work Tool Steel by Laser Powder Bed Fusion Utilizing Powder Mixtures Including Grinding Chips: Assessing Chemical Homogeneity and Achievable Hardness

open access: yesAdvanced Engineering Materials, Volume 28, Issue 1, January 2026.
Grinding chips of high‐alloyed steel are prepared to be admixed to a starting powder mixture for laser powder bed fusion. A three‐stage preparation is performed, including washing in acetone, magnetic separation, and ball milling. The addition of 30% of grinding chips to the powder mixture allows the fabrication of dense samples.

Additively Manufacturable High‐Strength Aluminum Alloys with Coarsening‐Resistant Microstructures Achieved via Rapid Solidification

open access: yesAdvanced Materials, Volume 38, Issue 4, 16 January 2026.
Rapid solidification in laser additive manufacturing facilitates the precipitation of metastable phases in aluminum alloys. These metastable phases significantly enhance the strength by forming a high‐volume fraction of precipitates with an order of magnitude reduced sizes and smaller interspacing, effectively impeding dislocation motion. Consequestly,

Shapeshifting Nanocatalyst for CO2 Conversion

open access: yesAdvanced Materials, Volume 38, Issue 2, 8 January 2026.
A multi‐modal in situ characterization of Ag‐Cu nanoparticles during CO2 photoreduction sheds light on dynamic transformations occurring during reaction. The Cu(core)‐Ag(shell) nanoparticles present the Ag replacement by Cu atoms. Ag is trapped at the subsurface forming a Ag‐Cu‐O phase, and the nanoparticle spreads over the substrate.
