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 study takes W from printing - DED and LPBF to cracking and characterization via high energy synchrotron x-ray diffraction experiments (DXD). While microstructure was examined for porosity and cracking, DXD experiments show the cracking behavior and a deeper understanding into the relationship between alloying. Results show how alloying and process parameter selection can lead to reduction in defects during laser powder bed fusion of tungsten and its alloys as well as the effects of alloying on cracking. |
