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,

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

open access: yesEngineering 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 ...

Photosensors used to maintain welding electrode-to-joint alignment [PDF]

open access: yes, 1965
Photosensors maintain electrode-to-joint alignment in automatic precision arc welding. They detect the presence and relative position of a joint to be welded and actuate a servomechanism to guide the welding head accordingly thus permitting alignment for
