High strength, oxidation resistant refractory alloys are difficult to fabricate for commercial use in extreme environments.
Gas metal arc welding (GMAW) wire arc additive manufacturing (WAAM) processes use inert shielding to protect the weld arc during material deposition, but do not protect the trailing bead, which can lead to weld issues varying from low finish quality to diminished material prop
As additive manufacturing technologies advance and 3D-printers get larger, there is a constant need for larger extruders with higher throughput to construct larger objects at reasonable time.
The first wall and blanket of a fusion energy reactor must maintain structural integrity and performance over long operational periods under neutron irradiation and minimize long-lived radioactive waste.
ORNL has developed a new hybrid additive manufacturing technique to create complex three-dimensional shapes like air foils and wind generator blades much more quickly.
Electrical utility substations are wired with intelligent electronic devices (IEDs), such as protective relays, power meters, and communication switches.
