Which outcome results when dislocations occur in a crystal lattice during additive manufacturing?

A)Increased grain boundary corrosion rate
B)Enhanced material elasticity and strength
C)Decreased probability of brittle fracture
D)Reduced thermal expansion coefficient magnitude

💡 Explanation

The grain boundaries have increased corrosion because the process of strain hardening builds up due to dislocation pile-up. Strain hardening will result in localized electrochemical potential gradients because this increases electrochemical activity rather than uniform material behavior.
