  • Digital imaging analysis of microstructures as a tool to identify local plastic deformation = Digitalna analiza posnetkov mikrostruktur kot orodje za ugotavljanje lokalne plastične deformacije
    Suban, Marjan ; Cvelbar, Robert ; Bundara, Borut
    This paper presents a methodology to detect plastic deformation on micro level. The analysis based on statistical data describing the morphological and crystallographic textures of asample ... microstructure, obtained from an optical microscopy using digital imaging analysis. Important parameters necessary to describe a microstructure were identified as grain size and grain orientation distributions. Change in weighted product of these two parameters, grain size as area of grain and grain orientation as moment of inertia of grain can represent a measure to identify plastic deformation on small area. Demonstration of applicability wasperformed on a real object as part of failure analysis of ruptured pipe in thermal power plantboiler. Presented analysis leads to the fast identification of the local plastic deformation and, in a case of periodical analysis of the same sample can even be used as a measure to identify creeping.
