Laser Powder Bed Fusion of Alumina: Effects of Scanning Strategies on External and Internal Defects

Advanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
This study investigates how scanning strategies affect pure alumina in laser powder bed fusion. Linear 45° scanning yields uniform surfaces but high porosity, while the island‐concentric strategy provides higher density with through‐holes favorable for infiltration. Findings highlight pathways toward optimizing defect‐free alumina parts.

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.

Comparison of Micro Al6061-12%TiB2 with Nano Al6061-12%TiB2 Composite

Journal of Advances in Mechanical Engineering and Science, 2016
Generally, attenuated actual composite materials consist of accretion like fibre, fillers and particles and are cast in a set of ceramics, metals or polymers. Owing to the backdrop of attenuated abstracts like aluminium oxide, silicon carbide, graphite etc, the composites are hardly abased.
