High Performance Light-Weight High-Entropy Alloys

DOE-NETL, PA, United States

TECHNOLOGY SUMMARY

NETL researchers have developed new, lighter, high-entropy alloy (HEA) formulations that have superior performance to conventional alloys and exhibit excellent balance among density, strength, ductility, high-temperature stability, oxidation resistance. A wide range of alloy densities can be tailored for particular applications by element selection and relative atomic fraction.

Primary Application Area: Materials & Chemical

Technology Development Status: Concept

Technology Readiness Level: TRL 4

FIGURES OF MERIT

Value Proposition: NETL’s HEAs overcome problems with current lightweight alloys such as oxidation, lower strength, 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.
