Sem brittle fracture
http://vgoinc.com/general/fractures-in-the-sem WebIntergranular 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. [1] The more commonly seen transgranular fracture, occurs when the crack grows through the material grains.
