Description
Intermetallic alloys like e.g. Iron-Aluminides, Titanium-Aluminides or Molybdenum-Silizides are prospective materials for high-temperature applications. For additive manufacturing (AM) intermetallic structural materials are particularly challenging due to their high melting points, oxygen susceptibility and low temperature brittleness. The feasibility of manufacturing intermetallics with laser additive manufacturing (LAM) is demonstrated and recent results in characterizing rapidly solidified material with respect to correlations between process, composition and microstructures are presented. Results on mechanical properties of AM intermetallic materials are comparatively discussed with regard to applications and conventional production methods. Current challenges, e.g. homogenous distribution of alloying elements and applicability are addressed.
