Which outcome occurs when a polycrystalline turbine blade experiences prolonged high-temperature creep?

💡 Explanation

The increase in voids causes cavitation, because grain boundary sliding occurs via vacancy diffusion at elevated temperatures. Intergranular cavitation therefore accelerates crack growth, rather than other plastic deformation mechanisms that would manifest at lower temperatures.
