The development of laser-based additive manufacturing (Powder Bed Fusion Laser Beam, PBF-LB) of these carbide grades does not go beyond feasibility studies. Cracking and the unexplained formation of undesirable cobalt-tungsten carbides prevent their use as tool materials. The aim of this work is the development of the PBF-LB process with subsequent post-treatment for carbides with 12 wt.- LB - PUB:(DE-HGF)11 DO - DOI:10.18154/RWTH-2024-04702 UR - https://publications.rwth-aachen.de/record/985630 ER -
