Which consequence results when dislocations impede grain boundary movement in polycrystalline steel?

A)Increased material yield strength
B)Decreased thermal conductivity
C)Enhanced magnetic permeability
D)Reduced corrosion resistance

💡 Explanation

Grain boundary movement controls plastic deformation in steel; dislocation pile-up causes strain hardening, therefore increasing yield strength because grain boundaries restrict slip, rather than weakening the material, enhancing magnetism, or affecting corrosion.
