← ScienceWhich outcome occurs when annealing a metal containing a high density of dislocations?
A)Increased grain size via dislocation climb✓
B)Reduced electrical conductivity via increased scattering
C)Elevated tensile strength via work hardening
D)Decreased corrosion resistance via precipitate formation
💡 Explanation
When a metal with high dislocations is annealed, dislocation climb occurs because thermal energy allows atoms to diffuse, enabling dislocations to move past obstacles and annihilate, resulting in grain growth. Therefore increased grain size results, rather than reduced conductivity, elevated strength, or decreased corrosion, which require separate conditions.
