= Transgranular fracture
{wiki=Transgranular_fracture}
Transgranular fracture refers to a mode of fracture in materials, particularly metals and ceramics, where the crack propagates through the grains of the material rather than along the grain boundaries. This type of fracture typically indicates that the material has a relatively high level of strength and ductility, as the fracture does not follow the path of least resistance. In transgranular fractures, the crack moves inside the grains, often resulting in fracture surfaces that show characteristic features according to the crystallographic orientation of the grains.
