Which risk dramatically increases when sustained high localized stress fractures the atomic lattice of a gas turbine blade?

💡 Explanation

Fracturing the atomic lattice enables easier propagation of stress concentrations and grain boundary sliding sites due to increased dislocation mobility, therefore accelerating fatigue crack propagation, rather than deceleration, because the lattice defect density is now increased.
