Fracture micromechanisms in the crack propagation zone for specimens with different-shaped notches.
| Test temperature | Notch shape | V | U | I |
| | Dimpled ductile fracture | | Brittle (flat cleavage facets) | Brittle (cleavage facets) | Brittle (cleavage facets + local microdimples) | | Brittle fracture with cleavage facets | Brittle fracture with cleavage facets and local microcracks | Brittle fracture with cleavage facets |
