What key alloying elements improve their high-temperature performance?

Core additive elements include chromium for anti-oxidation and anti-corrosion layers, tungsten and molybdenum to strengthen the matrix against creep deformation, aluminum and titanium to form precipitated reinforcing phases, plus boron and rare earths to refine grain boundaries. Each element targets different defects under extreme heat. Proper matching of elements prevents grain sliding, surface oxidation and long-term stress deformation during continuous high-temperature operation.
