What Wikipedia says

In materials science, a grain boundary is the interface between two differently oriented grains, or crystallites, of the same phase in a polycrystalline material. Grain boundaries are two-dimensional defects in the crystal structure, and tend to decrease the electrical and thermal conductivity of the material.
