← ScienceWhich risk increases when a turbine blade's crystal lattice misaligns?
A)Torsional resonance amplifies vibrations
B)Creep rate accelerates dramatically✓
C)Passivation layer forms spontaneously
D)Work hardening becomes unpredictable
💡 Explanation
Increases in creep rate occur because grain boundary sliding is enabled by increased space at dislocations, weakening the material's resistance to deformation under stress at elevated temperatures. The resulting failure of the lattice lowers resistance to creep, therefore accelerated creep rate, rather than vibrational or passivation effects.
