Abstract Scope |
This study examines microstructure and mechanical properties of pure tungsten and tungsten alloys additively manufactured by Directed Energy Deposition and Laser Powder Bed Fusion. Builds were deposited on a refractory metal baseplate and in an inert atmosphere. The microstructure, cracking, and porosity of the tungsten & tungsten alloy cubes was also assessed. High-temperature mechanical properties of the printed samples were investigated. Results showed how alloying and process parameter selection can lead to reduction in defects during AM of tungsten and its alloys and the effects of alloying on high temperature properties. |
