LLNL scientists identify the causes of crack formation in 3D printed tungsten 

Researchers from Lawrence Livermore National Laboratory (LLNL) have identified the reasons behind microcracking observed in tungsten during additive manufacturing. By combining simulations with high-speed video, the researchers were able to visualize the Ductile-to-Brittle Transition (DBT) of tungsten during 3D printing in real-time. Leveraging their monitoring technique, the team pinpointed variables such as residual stress, strain […]
