Single crystal superalloy, an alloy manufactured with a single crystal as a unit. Its alloying degree is relatively high, which makes up for the defects of serious segregation, poor hot workability, and difficult forming in traditional casting and forging superalloy ingots. At present, the fourth-generation single crystal superalloys that can be applied on a large scale have a temperature bearing capacity of 1140°C.
Because of this "extreme high temperature resistance" feature, it is more used in the manufacture of turbine blades for aerospace engines. Turbine blades made of single-crystal superalloys can stably suck high-temperature and high-pressure airflow into the combustor to maintain engine operation. At the same time, the single crystal superalloy has strong thermal processing performance. When using single crystal superalloy materials to manufacture turbine blades, craftsmen can also explore and design more industrial structures such as "boundary layer cooling design" to improve the efficiency of high-temperature-resistant blades.
