High-niobium titanium aluminum alloy is a polycrystalline high-temperature alloy metal that is strengthened by solid solution and precipitation. The density of high-temperature and high-performance high-niobium titanium-aluminum alloy is about half that of nickel-based high-temperature alloys. Using it to make high-temperature engine parts can greatly reduce the weight of the engine. , thereby improving the thrust-to-weight ratio of the engine.

The application of high-niobium titanium aluminum alloy will open up new developments in important fields such as aerospace, ships, and automobiles, and enable breakthrough development of existing equipment.

High-temperature resistant materials are commonly used to make turbine blades for jet engines. During the work process, the turbine blades of modern jet engines usually have to withstand high temperatures of 1,600-1,800 degrees Celsius, as well as wind speeds of about 300 meters per second, and the resulting huge air pressure, making the working environment extremely harsh. Modern turbine blades are usually made of directionally solidified single-crystal materials, and air-cooling channels must be opened inside. The process is extremely complex and is known as the crown jewel of modern industry. The new high-temperature and high-performance high-niobium titanium aluminum alloy can further improve the high-temperature resistance of turbine blades, allowing the engine air inlet temperature to be increased, thereby increasing engine thrust.
