Intergranular fracture, intergranular cracking or intergranular embrittlement occurs when a crack propagates along the grain boundaries of a material, usually when these grain boundaries are weakened. The more commonly seen transgranular fracture, occurs when the crack grows through the material grains. [1] the more commonly seen transgranular fracture, occurs when the crack grows through the material grains.

This usually occurs when the phase in the grain boundary is weak and brittle (such as. Intergranular fracture is the propagation of cracks along the grain boundaries of a metal or alloy. What is the weakest link for intergranular crack propagation mechanism? It is likely that intergranular crack propagation occurs owing to the repeated initiation of cracks and their coalescence, which is associated with plastic strain localization at the crack tips, and not because of successive crack blunting and resharpening.
