The developed alloys exhibited a thermal conductivity of 170-190 % level (160-180 W/(m K)), a fluidity of 60-85 % level, and an equalor higher ultimate tensile strength compared to those of an ADC12 alloy. In each developed alloy system, the thermal conductivity and the strength decreased and increased, respectively, as the content of the major alloying elements, Mg and Si, increased. The fluidity was inversely proportional to the Mg content and directly proportional to the Si content. The Al-(1.0-1.5)Si-1Fe-1Zn alloys showed better thin-wall castability due to their lower surface energy. In the experimental aluminum alloys with a low Si content, the fluidity was mainly dependent on the melt surface energy, the Al dendrite coherency point (DCP), and the first intermetallic crystallization point (FICP), rather than on the solidification interval, latent heat, or the viscosity"},{"@xml:lang":"sl","#text":"Za razvoj aluminijeve zlitine, ki združuje dobro toplotno prevodnost z dobro livnostjo in možnostjo eloksiranja, se predvideva, da sta dobro izhodišče aluminijevi zlitini z majhno vsebnostjo Si, kot sta Al-(0,5-1,5)Mg-1Fe-0,5Si in Al-(1,0-1,5)Si-1Fe-1Zn. Razvite zlitine so pokazale, da je toplotna prevodnost med 170-190 % (160-180 W/(m K)), livnost med 60-85 % in enaka natezna trdnost, kot jo ima primerjalna zlitina ADC12. V vsakem razvitem sistemu je toplotna prevodnost naraščala in trdnost padala, ko je naraščala vsebnost glavnih legirnih elementov Mg in Si. Tekočnost je bila obratno sorazmerna z vsebnostjo Mg in sorazmerna z vsebnostjo Si. Zlitina Al-(1,0-1,5)Si-1Fe-1Zn je pokazala boljšo livno sposobnost pri tankih stenah zaradi manjše površinske energije. Pri preizkusnih aluminijevih zlitinah z majhno vsebnostjo Si je bila tekočnost predvsem odvisna od površinske energije taline, koherenčne točke Al-dendritov (DCP) in prve točke strjevanja (FICP) intermetalne zlitine in manj od intervala strjevanja, latentne toplote ali viskoznosti"}],"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-2K9RZZQS","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-2K9RZZQS"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-2K9RZZQS/0fe53de3-735a-4289-9fcb-277d57a79fe6/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-2K9RZZQS/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-2K9RZZQS"}}}}
