Which outcome occurs when exhaust gas temperature exceeds the turbocharger turbine material's limit?

💡 Explanation

When exhaust gas temperature exceeds the limit, creep deformation occurs because high temperatures and stresses cause turbine blade atoms' plastic deformation over time, weakening them. Therefore creep weakens the blades, rather than surge, coking, or premature wastegate failure, which arise from compressor instability, oil degradation or mechanical wear issues.
