Abstract

Highlights: 316L samples were fabricated in the vacuum L-PBF at the VED of 7 kJ/mm 3 and higher. The microhardness has an average level of 242 HV0.05. The microhardness is not affected by the VED between 1.33 and 16.00 kJ/mm 3 . The microhardness was improved by more than 30% when 5 wt% of TiN was added.
