Wire Arc Directed Energy Deposition of Aluminum–B4C Composites

International Journal of Applied Ceramic Technology, Volume 23, Issue 2, April 2026.
ABSTRACT The scalable fabrication of structural‐grade aluminum metal matrix composites (A‐MMCs) remains constrained by inherent limitations of conventional processing routes and laser‐based additive manufacturing (AM) methods. In this work, we demonstrate the development of a hybrid wire arc directed energy deposition (WA‐DED) platform for the near‐net‐
