AFFILIATION:   U.S. Department of Energy (DOE) National Energy Technology Laboratory, Pittsburgh, Pennsylvania, United States

TECHNOLOGY SUMMARY

Track: Advanced Materials
Area: Advanced Manufacturing
Tech Readiness: TRL 4

Tech Brief: NETL researchers have developed new, light weight, high performance , high-entropy alloy (HEA). ICME approaches were used to design HEA with range of densities. These alloys have the potential to exhibit and excellent balance, density, strength, ductility, high-temperature stability, and oxidation resistance.

FIGURES OF MERIT

Value Proposition: NETL’s HEAs overcome problems with current lightweight alloys such as oxidation, weakness, and operating temperature limitations. The new alloy formulations provide enhanced strength in a wide temperature range, resistance to oxidation and corrosion, and are economically competitive when compared to conventional alloys.
