Damaging Micromechanisms Characterization in Pearlitic Ductile Cast Irons

In this work, the damaging micromechanisms in a pearlitic DCI have been investigated by means of the Scanning Electron Microscope (SEM) observation of the specimen lateral surface during the tensile tests (“in situ” tests). Damaging micromechanisms development has been analyzed, focusing both the role of the graphite nodules and the cracks initiation and propagation in the pearlitic matrix.
