Porous metallic materials can be made from liquid metal, from powdered metal, metal vapours, or from metal ions. The aim of this research was to verify the possibilities of producing metallic foams by conventional foundry processes, to study the process conditions as well as the physical and mechanical properties of the metal foams produced. The experiments demonstrated the possibility of manufacturing castings with both a regular cellular structure and a solid skin in a single casting operation using different kinds of preform made from commonly used resin-bonded core mixtures. From the perspective of the need to destroy the preforms after the metal's solidification it seems a very interesting prospect to produce preforms from different salts"},{"@xml:lang":"sl","#text":"Primerna pot za zmanjšanje mase izdelanih delov, ne da bi občutno vplivali na njihovo trdnost, je uporaba poroznih kovinskih materialov z različno notranjo razporeditvijo namerno povzročenih praznih jamic. Porozne kovinske materiale se lahko izdela iz staljene kovine, kovinskih prahov, kovinskih par ali iz kovinskih ionov. Namen raziskave je bil preveriti možnost izdelave kovinskih pen po navadnem livarskem postopku, študij pogojev procesa, fizikalne in mehanske lastnosti izdelane kovinske pene. Izvršeni poskusi so pokazali možnost izdelave ulitkov z urejeno celično strukturo in čvrsto skorjo z eno livarsko operacijo z uporabo različnih predoblik, izdelanih iz navadnih mešanic za jedra. S stališča potrebne razgradnje predoblike, potem ko se kovina strdi, se zdi konkurenčna izdelava predoblike iz različnih soli"}],"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-QAJRPSTN","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-QAJRPSTN"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-QAJRPSTN/f4962b5f-985e-41c7-9b42-266eb4f8c51d/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-QAJRPSTN/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-QAJRPSTN"}}}}
