← ScienceWhich outcome arises when dislocations propagate through a crystal?
A)Work hardening increases tensile strength✓
B)Increased grain increases current density
C)Annealing reduces void formation rate
D)Quenching forms a homogeneous structure
💡 Explanation
Work hardening occurs from dislocation pile-up during plastic deformation; because this entanglement obstructs further dislocation motion, it increases the material's yield strength; therefore tensile strength increases rather than the others because it involves lattice alterations influencing resistance.
