A Correct answer
Explanation

Superalloys are specifically designed for extreme environments like gas turbine engines where temperatures exceed 1000°C. They maintain strength at high temperatures, resist creep deformation, and withstand oxidation and corrosion. Common superalloys include Inconel, Waspaloy, and Rene alloys which contain nickel, cobalt, and other strategic elements.
