What is the limitation of superalloys?

Answer 1

Superalloys, while highly resistant to extreme temperatures and corrosion, face limitations such as high cost and complex fabrication processes. Their performance can degrade under certain conditions, such as prolonged exposure to high temperatures, leading to issues like creep and fatigue. Additionally, the heavy density of many superalloys can make them less suitable for weight-sensitive applications, such as in aerospace. Finally, the availability of raw materials for some superalloys can also pose supply chain challenges.
