Using the radioactive tracer sectioning method the bulk and grain boundary diffusion of ?$^{59}Fe$? was determined in Alloy 800 in the temperature range 800 to 1000°C. In Alloy 800H the activation energy of grain boundary diffusion of ?$^{59}Fe$? is (209?$\\pm$?17) kJ/mol. The use of the approximation of Suzuoka was confirmed by autoradiographs. Dissolved elements especially P increased the activation energy on the grain boundary diffusion of Fe by their segregation to the grain boundaries and by increasing carbide precipitation at the grain boundaries. The same materials - aged at 800°C for 100 h - were usedfor creep experiments under constant load and constant temperature. The chemical composition of the creep cavities and grain boundaries were analysed by Auger electron spectroscopy (AES). For Alloy 800 + 0.09 wt-% P an enrichment of about 14 at-% P was observed at the grain boundaries. No correlation of creep cavity formation and diffusivity could be found. The addition of P clearly enhances the creep strength of Alloy 800; this can be explained by phosphides in the grains and by enhanced precipitation of ?$Cr_{23}C_6$? on the grain boundaries during the creep process"},{"@xml:lang":"sl","#text":"Raziskali smo difuzijo, segregacije in lezenje, da bi ugotovili vpliv nečistoč na mikrostrukturo, lastnosti lezenja in samodifuzijo v različnih industrijskih Alloy 800 in v laboratorijsko izdelanih Alloy 800 z dodtakom P in S. Difuzija ?$^{59}Fe$? v osnovnem materialu in po mejah zrn v Alloy 800 je bila izmerjena z metodo radioaktivnih preiskav presekov, v temperaturnem področju od 800 do 1000°C. Za zlitino Alloy 800 H je aktivacijska energija difuzije ?$^{59}Fe$? po mejah zrn (209 ?$\\pm$?17) kJ/mol. Uporaba Suzuouka aproksimacije je bila potrjena z autoradiogrami. Raztopljeni elementi, posebno P zvišajo aktivacijsko energijo difuzije Fe po mejah zrn s tem, da segregirajo na mejah zrn in zvišajo precipitacijo karbidov na mejah zrn. Isti material staran 100 ur na 800°C je bil uporabaljen za eksperimente lezenja pod konstantno obremenitvijo in pri konstantni temperaturi. Kemijska sestava jamic, nastalih pri lezenju in mej zrn je bila določena s Spektroskopijo na Augerjeve elektrone (AES). Pri zlitini 800 z 0,09 mas% P je bila izmerjena na mejah zrn obogativev s 14 at.% P. Nobene povezave med difuzijo in tvorbo jamic pri lezenju ni bilo mogoče najti. Dodatek P jasno poveča odpornost Zlitine 800 pri protilezenju; kar lahko razložimo s fosfidi v zrnih in s povečano precipitacijo ?$Cr_{23}C_6$? na mejah zrn med procesom lezenja"},{"@xml:lang":"sl","#text":"Nadaljuje se kot: Materiali in tehnologije"}],"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-J42IHQDS","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-J42IHQDS"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-J42IHQDS/10171107-a62d-477c-bd35-4276f91b63f2/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-J42IHQDS/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-J42IHQDS"}}}}
