Robust Metal Alloys
Project Innovation + Advantages:
The team led by Oak Ridge National Laboratory (ORNL) will develop new cast alumina-forming austenitic alloys (AFAs), along with associated casting and welding processes for component fabrication. ORNL and its partners will prototype industrial components with at least twice the oxidation resistance compared to current cast chromia-forming steel and test it in an industrial environment. These innovations could allow various industrial and chemical processing systems and gas turbines to operate at higher temperatures to improve efficiencies and reduce downtimes, thus providing cost and energy reductions for a wide range of energy-intensive applications.
If successful, ORNL's new cast alumina-forming alloys could provide a more energy-efficient effective alternative to chromia-scale alloys.
