Which risk increases when a turbine blade alloy cools, forming uneven precipitate concentrations along grain boundaries in the nickel-based superalloy lattice?

💡 Explanation

Creep failure risk increases because precipitate inhomogeneity causes localized stress concentration, leading to accelerated creep via Coble creep along grain boundaries; therefore, uneven precipitation is detrimental rather than improving strength with uniform dispersion or affecting other properties directly.
