Observing in higher magnification it is possible to see that the fracture presents a mixture of ductile and brittle micromechanisms. The intergranular mechanism indicates that the material is embrittled and the dimples indicate localized overloading conditions.

ML00148 — Brittle Fracture of a 420 SS Barrel NutM - Martensitic Stainless SteelP - Barrel NutAp - LiftingCd - Heat Treatment Defect
Detail of the ductile dimples and the brittle intergranular micromechanisms. This evidence (a mixture of mechanisms) suggests that the embrittlement is localized in some regions of the material.
