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"},{"@xml:lang":"sl","#text":"V prispevku je predstavljena metodologija za odkrivanje plastične deformacije na mikroravni. Metoda temelji na podlagi statističnih podatkov, ki opisujejo morfološke in kristalografske teksture mikrostrukture. Vir podatkov je digitalna analiza posnetkov, pridobljenih iz optične mikroskopije. Kot pomembna parametra, potrebna za opis mikrostrukture, sta opredeljena distribucija velikosti zrn in usmerjenosti zrn. Sprememba tehtanega zmnožka teh dveh parametrov: velikosti zrna kot površine zrna in usmerjenosti zrna kot vztrajnostni moment zrna, je lahko merilo za identifikacijo plastičnih deformacij na majhnem področju. Za prikaz uporabnosti metode je bila izvedena analiza na realnem objektu kot del analize poškodb počene cevi v kotlu termoelektrarne. Predstavljena analiza omogoča hitro identifikacijo lokalne plastične deformacije, pri časovno zaporedni analizi istega vzorca pa se lahko celo uporablja za identifikacijo lezenja"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-JPQZ1M1L","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-JPQZ1M1L"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-JPQZ1M1L/7ca95d61-cddc-4b2d-ac4e-28f6f6994eba/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Inštitut za kovinske materiale in tehnologije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-JPQZ1M1L/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-JPQZ1M1L"}}}}
