Intergranular fracture

An intergranular fracture is a fracture that follows the grains of the material, where cracks that take place along the grain boundary. In a wall of bricks it would correspond to a fracture that takes place in the mortar that keep together bricks. In metals with multiple lattice organizations, when one lattice ends and another begins, the fracture changes direction to follow the new grain. This results in a fairly jagged looking fracture with straight edges of the grain and shiny surface may be seen.
