Volatile alloying elements modulate laser-induced arc stability: A material-dependent interaction mechanism

Journal of Materials Research and Technology
It is generally known that a laser can stabilize an arc. However, some numerical studies suggested that the laser-induced metal vapor decreased the temperature and electrical conductivity of arc plasma in hybrid laser-arc processing.In this study, the ...

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

Advanced 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,

Surface Evolution and Corrosion Response of SLM–Cast Hybrid Aluminium Alloys Before and After Electrochemical Exposure

Engineering Reports, Volume 8, Issue 1, January 2026.
Hybrid aluminium structures combining SLM and casting exhibit distinct corrosion behaviors linked to microstructural features. Electrochemical testing and surface analyses revealed that finer, uniformly dispersed grains enhance passivation and reduce corrosion rates, while coarser‐grained regions show greater susceptibility to localized attack ...
