Abstract Scope |
Although tungsten (W) is known for its brittle nature at room temperature, recent advancements in additive manufacturing saw a surge in pursuing additive manufacturing (AM) of W and W alloys. This examines the microstructure of pure W and W alloys printed via powder feed laser based - directed energy deposition (DED-LB). While microstructure was examined for porosity and cracking, micro-segregation is studied along with studying for high temperature strength properties. Results show how alloying and process parameter selection can lead to reduction in defects during DED-LB of W and its alloys as well as the effects of alloying on cracking |
