Abstract

The use of ceramic nanoparticles as inoculants can promote equiaxed microstructures and reduce solidification cracking during Laser Powder Bed Fusion (L-PBF) of high-strength aluminum alloys. However, concerns about particle agglomeration and health risks have shifted interest toward larger particles, though their effectiveness and optimal size and concentration remain unclear. This study examines how inoculant particle size and fraction affect the physical and rheological properties of gas-atomized AA2017 powder and evaluates their impact on L-PBF samples. Titanium carbide (TiC) particles of three sizes (45 nm,
