A novel cobalt (Co)- and nickel (Ni)-based high-entropy superalloy (CoNi-HESA) capable of withstanding higher operating temperatures could prove a step toward more powerful and fuel-efficient aircraft engines.
Scientists have developed a chromium-molybdenum-silicon alloy that withstands extreme heat while remaining ductile and oxidation-resistant. It could replace nickel-based superalloys, which are limited to about 1,100°C. The new material might make turbines and engines significantly more efficient, marking a major step toward cleaner, more powerful energy systems.
