Which mechanical consequence results when dislocations accumulate within polycrystalline material's lattice?

A)Increased material yield strength
B)Accelerated thermal conductivity decline
C)Enhanced piezoelectric coefficient
D)Reduced susceptibility to corrosion

💡 Explanation

Increased yield strength occurs because dislocation pile-up causes strain hardening, which impedes further plastic deformation via the dislocation _slip mechanism_. Therefore, the strength increases, rather than conductivity failing, as piezoelectricity and corrosion resistence are unrelated.
