Which condition occurs as crystal grain boundaries increase?

A)Increased material yield strength
B)Decreased thermal defect formation
C)Enhanced neutron moderation capacity
D)Reduced piezoelectric charge buildup

💡 Explanation

Grain boundaries impede dislocation movement; dislocation pile-up leads to increased strength via strain hardening because the mechanism of plastic deformation is blocked. Therefore, yield strength increases, rather than decreasing defect formation, which is influenced by temperature and composition.
