The aim of our work was to calculate the activation energy for different carbide particle sizes and particle spacings, using a modified equation for the creep rate calculation. For creep-resistant steel with a microstructure of ferrite matrix and a uniform distribution of M23C6 carbide particles the creep rate was calculated in the temperature range 540 °C to 630°C and a carbide particle size between 0.1 mum and 0.4 mum. An equal effect on the creep rate increase was found for all four carbide particle sizes. From the calculated creep rates a creep activation energy of 248.7 kJ/mol was calculated, independent of the particles size. The calculated creep activationenergy was found to be close to the self-diffusion activation energy in alpha-iron"},{"@xml:lang":"sl","#text":"Dosedanje raziskave kažejo povezavo med porazdelitvijo karbidnih delcev v martenzitu in hitrostjo pospešenega lezenja, pri čemer je hitrost lezenja odvisna od števila karbidnih delcev na enoto površine in njihove medsebojne razdalje. Cilj našega dela je bil izračun aktivacijske energije za različne velikosti karbidnih delcev in njihovih medsebojnih razdalj. Izračun je temeljil na modificirani enačbi za izračun hitrosti lezenja. Aktivacijska energija procesa lezenja je bila izračunana za jeklo, odporno proti lezenju, z mikrostrukturo iz ferita in enakomerno porazdelitvijo karbidnih izločkov M23C6. Izračun je bil izdelan za temperaturno območje od 540 °C do 630 °C in velikost karbidnih zrn med 0,1 mim in 0,4 mim. Rezultati izračuna so pokazali enako povečanje hitrosti lezenja za vse 4 velikosti karbidnih izločkov. Na podlagi hitrosti lezenja je bila izračunana tudi aktivacijska energija lezenjav vrednosti 248,7 kJ/mol, ki se je izkazala za neodvisno od velikosti izločkov. Izračunana aktivacijska energija procesa lezenja se le malo razlikuje od aktivacijske energije za samodifuzijo v alfa-železu"}],"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-6YJ7ZOKF","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-6YJ7ZOKF"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-6YJ7ZOKF/d1787e83-f971-4163-81a1-feb3900e2a56/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-6YJ7ZOKF/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-6YJ7ZOKF"}}}}
