The spring fracture was rusted and did not allow the fractographic analysis. The quasecleavage and intergranular fracture micromechanisms presented in this scanning electron microscopy image were obtained from the Charpy V broken testpiece that presented 15J of absorbed energy at room temperature (21°C).
