Researchers Develop Ultra-Hard Alloy Resistant to 1,400°C

Quick Summary:

• U.S.researchers have developed an ultra-hard copper-based alloy capable of withstanding temperatures up to 1,400°F (800°C).
• The alloy boasts a yield strength of 1120 megapascals (MPa), far exceeding carbon steel’s typical limit of ~700 mpa.
• Copper alloys traditionally known for conductivity are now showing promise for impressive toughness and high-temperature resistance.
• The breakthrough was achieved through nano-engineering by combining copper-lithium precipitates with tantalum layers, adding half a percent of lithium to alter the precipitate shape from spheres to stable cubes.
• Applications include use in extreme environments like hypersonic jets, nuclear reactors, fusion power plants, aircraft systems, power generation components, and weaponry.
