Question

Quizplus · Accepted Answer

Grain boundaries are considered surface defects because they occur at the surfaces between different grains or crystals within a material, affecting the material properties at these interfaces. Unlike point, line, or other types of defects, grain boundaries involve the area where the crystallographic direction of the lattice changes, which is essentially a two-dimensional defect.
