SUMMARY
Single crystals exhibit anisotropic properties due to variations in atomic arrangement and spacing along different lattice directions. For instance, graphite demonstrates greater strength in the axial direction compared to other orientations. In contrast, polycrystalline materials, such as most engineering alloys, tend to be isotropic because the random orientations of multiple grains average out these directional differences. The primitive cubic lattice illustrates this concept, as the distance to nearest neighbors varies significantly depending on the direction of measurement.
