← ScienceWhich consequence results when a crystal lattice contains dislocations?
A)Material's yield strength decreases.✓
B)Increased thermal conductivity occurs.
C)Enhanced piezoelectric effect arises.
D)Ferromagnetic order increases sharply.
💡 Explanation
Lattice dislocations disrupt the uniform atomic arrangement, permitting easier plastic deformation because movement along those dislocations requires less stress rather than perfectly aligned lattices. Therefore, the yield strength decreases; the others increase disorder.
