The paper shows the preliminary results of uniaxial tension tests on a pearlitic Ductile Cast Iron (DCI) by using the Acoustic Emission (AE) technique as well as the Scanning Electron Microscope (SEM) analysis.

Abstract
The paper shows the preliminary results of uniaxial tension tests on a pearlitic Ductile Cast Iron (DCI) by using the Acoustic Emission (AE) technique as well as the Scanning Electron Microscope (SEM) analysis. The experimental tests demonstrate the damage initiation and evolution occurring within the graphite nodules produce AE activity. The evaluation of the Shannon Entropy of the AE data is found to promising for the assessment of DCIs.File in questo prodotto:
