SiC or 3?$TiO_2$?+3C+4Al ?$\\to$? 3TiC+2?$Al_2O_3$?). In this way, two methods of processing for introducing larger amounts of fine SiC particles into a Al alloy melt without rejection of the reinforcement, and without unwanted chemical reactions between the matrix and the reinforcement were developed. The introduction of fine (less than 6?$\\mu$?m) rounded-off SiC particles combined with a significant reduction in casting and extrusion defects caused by cost effective HIP treatment without encapsulation results in superior tensile properties. Moreover, in a defect-free composite, high aspect ratio reinforcements like SiC whiskers and platelets can be successfully used in order to improve the mechanical properties of final parts"},{"@xml:lang":"sl","#text":"V delu je predstavljena nova livarska tehnologija za pridobivanje diskontinuirano ojačanih kompozitov z osnovo iz najrazličnejših Al zlitin.

SiC ali 3?$TiO_2$?+3C+4Al ?$\\to$? 3TiC+2?$Al_2O_3$?), ki potekajo na meji med keramičnimi delci in talino, oz. na kemijsko aktiviranem procesu omakanja keramičnih delcev s talino. Ugotovljeno je, da je izboljšanje mehanskih lastnosti končnih izdelkov mogoče doseči le z zmanjšanjem napak v materialu, ki nastajajo pri obdelavi taline in pri ekstrudiranju. Napake je najboljše odpraviti s HIP obdelavo končnih izdelkov. Raziskave so pokazale, da zagotavlja kombinacija livarskega načina priprave kompozita in HIP obdelave končnih izdelkov zelo ugodno razmerje med ceno in kvaliteto. Zaradi tega je omenjena tehnologija primerna za nadaljnje uvajanje diskontinuirano ojačanih kompozitov na osnovi aluminija v avtomobilsko industrijo"},{"@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-OHRDO2PY","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-OHRDO2PY"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-OHRDO2PY/7fdeeab5-87b8-45c8-83c9-4f030657693e/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-OHRDO2PY/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-OHRDO2PY"}}}}
