In general, pre-cursors consist of compacted mixture of metallic powder and foaming agent, which is foamed at a pre-determined temperature. Due to high temperature of foaming procedure, the foaming agent decomposes into a solid component that is built into the matrix material, and a gas component that causes foaming of the matrix material. Powder metallurgy is a method for making close-cell foams and it is the best selection, especially for the production of net-shape parts, providing excellent quality of end products. In our research work, powders, precursors and foams, made from different metallic powders (Al 99.7 % purity, AlSi12 alloy) with different foaming agents (TiH2, CaCO3, CaMg(CaCO3)2), were examined with different analytical techniques"},{"@xml:lang":"sl","#text":"Aluminijeve pene, narejene po postopku prašne metalurgije, so zelo odvisne od priprave prekurzorjev. Ti so narejeni iz stisnjenih prašnih delcev osnovnega materiala in penilnega sredstva ter penjeni pri določeni temperaturi. Zaradi visokih temperatur penilno sredstvo razpade na trdno snov, ki se vgradi v osnovni material, in plin, ki povzroči penjenje osnovnega materiala. Po postopku prašne metalurgije se izdelujejo aluminijeve pene z zaprto poroznostjo. Ta metoda je najbolj primerna za izdelavo kompleksno oblikovanih končnih oblik izdelkov. Pri našem raziskovalnem delu smo z različnimi analitskimi tehnikami raziskali kovinske prahove (Al, čistote 99,7 %, in zlitine AlSi12) in penilna sredstva (TiH2, CaCO3, CaMg(CaCO3)2), prekurzorje ter končne porozne materiale"}],"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-BHGABRE9","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-BHGABRE9"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-BHGABRE9/ce3ef0c4-33c9-46e0-98d1-295429176e72/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-BHGABRE9/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-BHGABRE9"}}}}
