Which outcome occurs during investment casting of turbine blades when environmental humidity spikes during shell drying?

💡 Explanation

Ceramic shell cracking from excessive moisture happens because moisture weakens bonds via increased capillary action during rapid evaporation weakening its load bearing ability; therefore cracking risk increases rather than alternatives like alloy segregation, which are material-related.
