Superalloys
Superalloys are rightly named due to their extraordinary mechanical properties and oxidation resistance at elevated temperatures. These alloys find application at most demanding service conditions like the hottest section of jet turbine engines, space shuttle engines etc. Some superalloys operate in applications that go as high as 90% of their melting point while maintaining its high temperature properties. Superalloys consist of three groups of alloys namely nickel based, cobalt based and iron-nickel based. Base metals are extensively alloyed to achieve its superior properties. Applications Superalloys display extraordinary resistance to mechanical and chemical degradation at temperatures close to their melting points.
