Micrography of a longitudinal section of the bolt at the thread fillet adjacent to the fracture, presenting a ductile cracking from the bottom of the fillet, propagating with a strong plastic deformation. The deformation lines of the cold formed process (thread cold rolling) are also deformed by the cracking propagation.

ML00120 — Ductile Rupture of a Carbon Steel Eye BoltM - Low Carbon SteelP - FastenerAp - AutomotiveCd - Overload
Micrographic detail of a longitudinal section of the bolt at the bottom of the thread fillet adjacent to the fracture, presenting a ductile cracking propagating with a plastic deformation. The deformation lines of the cold formed process are also deformed by the cracking propagation and there are some other small secondary cracks at 90° from the principal cracking.
