• dimpled ductile texture

Fractures and their profiles are diagnosed by macro- and micro-fractographic analysis after impact bending tests of Charpy specimens of a high-ductility steel of strength class X80. The results of the analysis of fracture surfaces and fracture diagrams are used to determine the unit amount of energy expended on ductile fracture in various zones in terms of the average length of the ridges (bridges) in the microstructure.
