Different amounts of carbon were obtained by varying the time of melting. The resulting samples had large rod-like carbides with volume fractions 0.6 % to 3.7 % Ti2AlC in the lamellar matrix consisting of the alternating lamellas of g-TiAl and a2-Ti3Al phases. It was found that the grain size of the matrix decreases with the increasing volume fraction of Ti2AlC carbides from 430 %m to 35 %m. In addition, finer carbides with a similar composition were observed. Their size was below 1 %m and they appear mainly at the grain boundaries and also inside the lamellar grains. Compression testing revealed that all the samples had a relatively high yield strength at elevated temperature, from 917 MPa to 623 MPa at 600 °C and from 608 MPa to 547 MPa at 800 °C, but the best strength and the best yield strength were found for the sample with the lowest amount of the large rod-like Ti2AlC carbides. From these results it is concluded that the strengthening at an elevated temperature is a result of C in the solid solution and small carbide precipitates rather than of the rod-like Ti2AlC carbides"},{"@xml:lang":"sl","#text":"Intermetalne zlitine g-TiAl z množinskim deležem itrija x = 0,3 % in brez njega ter z različno vsebnostjo množinskega deleža ogljika od 0,9 % do 1,6 % so bile izdelane z vakuumskim indukcijskim pretaljevanjem v grafitnem lončku. Različne vsebnosti ogljika so bile dobljene pri različnih časih taljenja. Dobljeni vzorci so imeli volumenski delež Ti2AlC od 0,6 % do 3,7 % velikih paličastih karbidov v lamelarni osnovi iz lamel faz g-TiAl in a2-Ti3Al. Ugotovljeno je bilo, da se z večanjem volumenskega deleža Ti2AlC-karbidov velikost zrn osnove zmanjšuje od 430 %m do 35 %m. Opazilo se je tudi, da imajo drobnejši karbidi podobno sestavo. Njihova velikost je manjša od 1 %m, pojavljajo se večinoma po mejah zrn in tudi v lamelarnih zrnih. Tlačni preizkus je odkril, da imajo vsi vzorci relativno visoko mejo tečenja pri povišanih temperaturah: od 917 MPa do 623 MPa pri 600 °C in od 608 MPa do 547 MPa pri 800 °C. Najvišjo trdnost in najvišjo mejo tečenja je imel vzorec z najmanjšo vsebnostjo velikih, paličastih Ti2AlC-karbidov. Iz rezultatov je razvidno, da je utrjevanje pri povišanih temperaturah bolj posledica ogljika v trdni raztopini in drobnih karbidnih izločkov kot pa velikih paličastih Ti2AlC-karbidov"}],"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-M681MWSR","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-M681MWSR"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-M681MWSR/6c3a4f07-18c6-40a1-afe5-0232663b140d/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-M681MWSR/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-M681MWSR"}}}}
