A High-Performance Alloy for Efficient Jet Engines
A high-performance alloy may lead to highly efficient jet engines, as Chromium, molybdenum, and silicon team up to confer oxidation resistance and more.
Despite fueling climate change, fossil fuels remain the mainstay of major industrial sectors such as aviation. But carbon emissions can fall if the efficiency of energy conversion from fossil fuels improves.
For jet engines, that requires pushing turbine operating temperatures beyond 1,150 °C. That switch means replacing the nickel-based “superalloys” used currently with materials that can withstand temperatures over 2,000 °C.
