Description
Additive manufacturing presents a new avenue for refractory metal that opens the door for development of improved refractory alloys for extreme environments that previously were inaccessible. This technology utilizes novel alloys that have favorable characteristics for these extreme uses, notably the ability to withstand high temperature, large temperature gradients, hypersonic speeds, provide high strength and are resistant to oxidation. These typically would be difficult to manufacture, but AM makes it possible to fabricate uniform and finely distributed microstructures. These alloys can be used in temperatures beyond what the nickel-based alloys currently use, at more than 1200 C. These alloys are oxidation resistant and strong, and are lighter than nickel and niobium currently used.
Benefits
- Can be used in extreme environments: high temperature and stress
- Resists oxidation
- Increased strength
- Easier to manufacture
- Withstands hypersonic speeds
Applications and Industries
- Aerospace
- Engine turbine manufacturers
