| Abstract Scope |
This study examines microstructure and mechanical properties of
pure tungsten and tungsten alloys additively manufactured by powder-feed directed energy deposition additive manufacturing. Cubes were deposited on a refractory metal baseplate. The layer height was experimentally decided as a function of powder,travel speed, and powder feed rate by the quantification of already printed cubes. The microstructure and cracking of the tungsten & tungsten alloy cubes was also assessed and the cause for porosity in the samples using DED process was studied. Results showed how alloying and process parameter selection can lead to reduction in defects during direct energy deposition of tungsten and its alloys. |
