Cover Story: A promising approach for the development of innovative materials in Directed Energy Deposition (DED-LB/M) is the use of premixed powders, consisting of a microscale host powder and at least one other powder species added as micro- or nanoparticles. In this way, the chemical composition and microstructural properties (phase fractions, precipitations, grain size, etc.) are specifically adapted to the starting material and the mechanical properties are adjusted in order to produce parts with outstanding practical properties that far exceed the performance of traditionally manufactured parts. In the context of the present study, the processing of AISI H11 tool steel powder blends enriched with carbon nanoparticles for the AM of tailored forging dies in DED-LB/M was the subject of scientific investigations. view this paper
