Er/Sc Co‐Doping Enabling Laser‐Powder Bed Fusion Aluminum Alloys With Superior Strength and Uncompromised Toughness

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT High‐strength aluminum (Al) alloys are usually unprintable by laser powder bed fusion (LPBF) due to the severe hot cracking along the columnar grains. Doping elements scandium (Sc) and/or zirconium (Zr) is an effective way to eliminate hot cracks by refining the grain size to nearly nanoscale levels.

Unlocking Exceptional Strengthening in Aluminum Alloys via Interstitial Cottrell Atmosphere Formation

Advanced Functional Materials, Volume 36, Issue 52, 29 June 2026.
Cyclic unloading‐aging‐reloading micro‐tensile tests under various aging durations and temperatures, combined with comprehensive microstructural characterization reveal that the yield point phenomenon in Aluminum‐Carbon (Al‐C) thin films originates from Cottrell atmosphere formation.

Solidification orientation relationships between Al3Ti and TiB2 [PDF]

, 2019
Orientation relationships (ORs) can form during solidification by a variety of mechanisms that are often difficult to distinguish after solidification. Here we study three ORs formed by the nucleation of Al3Ti on TiB2, and by the pushing and engulfment ...
