– How do jet engine turbine blades not melt?

Question

Jet engines work at a higher temperature that the melting point of Titanium Superalloy so how do they not melt?

Answer 1

I was responsible for the initial melting process of this component. The nickel based alloy goes through a rigorous triple melt process. VIM melting (void of atmosphere) , VAR and ESR remelting takes place after initial melt. Add in heat processing and very strict inspection process downstream.
