Abstract

The dynamics of the reinforced particles' migration remains unclear during the rapid non-equilibrium laser powder bed fusion (LPBF) process. Conducting real-time observations to obtain a comprehensive understanding of the reinforcements' movement is challenging due to the complex physical...
