Which risk increases when a Stirling engine cycle operates at excessively high temperatures?

💡 Explanation

Increased operating temperature accelerates creep; therefore, thermal fatigue rises at high temperature because vacancy diffusion increases, rather than other issues like reduced pressure which are separate failure modes at lower temperature.
