The deformation resistance is much lower on flame than on chimney side of the same exploited tube. The cause is the higher operation temperature on flame side, which modifies the micromorphology of the distribution of carbide precipitates in martensite grains. It is not possible to evaluate reliably the modification of initial steel properties solely on the base of microstructural examination and hardness measurements. The must reliable results are obtained by mechanical testing by slow straining under constant load at boiler operations temperature"},{"@xml:lang":"sl","#text":"Analizirana je mikrostruktura in določena je odpornost jekel X2OCrMoV121 in 10CrMo910 proti lezenju pri statični obremenitvi in pri temperaturi 580°C. Preizkušanci so bili izdelani iz cevi, ki so bile izrezane iz visokotlačnega parnega kotla po eksploataciji več 10 000 ur. Odpornost proti lezenju je mnogo manjša pri jeklu s plamenske kot z dimne strani iste cevi. Vzrok je višja temperatura med obratovanjem kotla, zaradi katere se je močno sprenila porazdelitev znotraj martenzitnih zrn. Na osnovi mikrostrukture in trdote je mogoče samo približno oceniti stopnjo zmanjšanja lastnosti jekla zaradi eksploatacije v parnem kotlu. Najbolj se obnese natezni preizkus pri konstantni obremenitvi in temperaturi obratovanja kotla"}],"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-0MFRUUX7","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-0MFRUUX7"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-0MFRUUX7/5b22781b-b5d5-4771-8784-292fbdb2a094/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:dataProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-0MFRUUX7/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-0MFRUUX7"}}}}
