Russian Scientists Identify Key Alloys for Aviation Industry

February 26, 2024

Russian researchers have pinpointed alloys with optimal properties for use in next-generation aircraft engines, capable of enduring high temperatures up to 1000 degrees Celsius. The study, funded by the Russian Science Foundation (RNF) and conducted by Belgorod State National Research University, focused on twelve alloys composed of niobium, chromium, titanium, and zirconium.

The findings revealed that alloys made of niobium and chromium, as well as a combination of niobium, titanium, and chromium, are particularly suited for aviation applications, offering enhanced strength and oxidation resistance. Contrary to previous beliefs that adding more elements would improve alloy characteristics, the study showed a niobium and chromium alloy to be three times stronger than its counterparts, including those with three or four metals.

Additionally, an alloy combining niobium, titanium, and chromium exhibited superior resistance to oxidation, outperforming niobium and titanium alloys and those with additional elements.
