Mitigating keyhole pore formation by nanoparticles during laser powder bed fusion additive manufacturing
Keyhole pore formation is one of the most detrimental subsurface defects in the laser metal additive manufacturing process. However, effective ways to mitigate keyhole pore formation beyond tuning laser processing conditions during keyhole mode laser melting are still lacking. Here we report a novel...
