Grain Boundary
Grain boundaries act as both protectors and weak points in metals, shaping their strength and durability

How do grain boundaries influence the mechanical strength and corrosion resistance of polycrystalline materials?
Grain boundaries improve electrical conductivity and prevent corrosion entirely.
Grain boundaries block dislocation motion, increasing strength, but also serve as sites for corrosion initiation.
Grain boundaries have no significant effect on material properties and are merely structural defects.
