Fractography of the broken Charpy V testpiece, in a high strength steel that absorbed 11 Joules at 20°C. Quasicleavage and dimples are the main fracture micromechanisms with some secondary cracks that appear to be intergranular, exactly as the fracture of the part.

Fractography of the broken tensile testpiece, in a high strength steel (about 260Ksi Yield Strength) that presented 10% elongation. The fracture micromechanism in a static test is quasicleavage and dimples, with some secondary cracks that appear to be intergranular, exactly as the fracture of the part.
