← ScienceWhich consequence results when interfacial lattice mismatch concentrates stress?
A)Increased tunneling barrier width
B)Accelerated grain boundary corrosion✓
C)Enhanced piezoelectric coefficient
D)Suppressed thermal expansion isotropy
💡 Explanation
Accelerated grain boundary corrosion results when interfacial lattice mismatch concentrates stress because grain boundaries become preferential sites for corrosion via galvanic corrosion effects. Corrosion occurs there rather than uniformly, therefore accelerating localized attack.
