Team designs nitride-reinforced NbMoTaWHfN refractory high-entropy alloy

A new generation of refractory alloys with excellent high-temperature performance is urgently demanded for aero-engines, gas turbines, and nuclear power plants. As the service temperature of their hot-ends is reaching 1800 °C or even higher, traditional superalloys can hardly fulfill the temperature demands. Mainly composed of refractory metal elements, refractory high-entropy alloys (RHEAs) exhibit enhanced strength at temperatures above 1,200° C, causing them to attract a great deal of attention.  Read More
