← ScienceWhich consequence results when metallic lattices experience stress?
A)Decreased electrical conductivity forms dislocation✓
B)Increased tensile strength via grain growth
C)Enhanced ductility from oxide formation
D)Elevated melting temperature, recrystallization occurs
💡 Explanation
Decreased electrical conductivity occurs because dislocation formation scatters electrons, hindering their movement through the lattice. The mechanism involves plastic deformation. Therefore, there is reduced conductivity, rather than improved strength, oxidation, or elevated temperature, these occur due to different mechanisms.
