Which performance loss accelerates in a jet engine when turbine inlet temperature exceeds design thresholds?

💡 Explanation

Exceeding the temperature threshold leads to increased vacancy diffusion; the mechanism causing creep deformation. Turbine blades elongate and lose shape because the engine runs hotter, therefore deformation increases and impairs efficiency, rather than other issues like fuel issues.
