← ScienceWhich 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.
