Which risk notably escalates when a turbine blade’s nickel superalloy lattice exhibits excessive creep?

💡 Explanation

Increased creep causes the blade to elongate excessively due to vacancy diffusion, enlarging the blade-tip clearance gap; therefore, efficiency drops significantly rather than uniform acoustic changes because creep primarily distorts the microstructure.
