Which of the following materials is most suitable for high-temperature applications in gas turbines?
Show Hint
- Aluminum
- Titanium
- Nickel-based superalloy
- Stainless steel
The Correct Option is C
Solution and Explanation
Gas turbines operate at high temperatures, requiring materials with high melting points and thermal stability.
Step 2: Evaluate options
Aluminum: Low melting point, unsuitable for high temperatures.
Titanium: Good strength, but limited at extreme temperatures.
Nickel-based superalloy: Designed for high heat and corrosion resistance.
Stainless steel: Moderate heat resistance, not ideal for turbines.
Step 3: Select best material
Nickel-based superalloys excel in high-temperature gas turbine applications.
