NICKEL-BASED ALLOY AND TURBINE WHEEL

Nickel-base superalloys are corrosion resistant high-temperature alloys typically used at service temperatures above 500°C. They usually contain significant amounts of up to 10 alloying elements including light elements like boron or carbon and heavy refractory elements like tantalum, tungsten, or rhenium. Superalloys display excellent resistance against creep, sulfidation, and oxidation even at temperatures close to their melting points. Due to their good properties at elevated temperatures, nickel-base superalloys have been widely used for aerospace, power generation, and automotive high temperature applications since their emergence in the 1950s. 

A Nickel Alloy turbine wheel refers to a component used in various industries, particularly in aerospace, power generation, and automotive applications, where high-performance and reliability are essential. This type of turbine wheel is typically made from a nickel-based superalloy, which offers exceptional high-temperature strength, corrosion resistance, and mechanical properties.
