Which outcome is accelerated in a jet engine turbine when hot exhaust gases cause creep deformation?

💡 Explanation

When prolonged high heat exposure causes creep, the turbine blades permanently deform due to thermally-activated atomic diffusion, distorting the airfoil shape and reducing aerodynamic efficiency. Therefore reduced fuel efficiency over time results, rather than noise, stall or surge which involve different aero/mechanical disruptions.
