The results of the experiments showed that the alumothermic reduction takes place in steel, but the products obtained with the reduction suggest that the reaction mechanism is more complicated and includes different metallic phases other than a simple reduction of pure elemental titanium. Two kinds of experiments were carried out, the alumothermic reduction of ilmenite in a steel melt and the alloying of the alumothermic mixture into the steel melt. The experiments were carried out in order to get a view of the phase boundary between the steel and reduced titanium and the metallic phases that occur during the reduction, before the dissolution of titanium in the steel melt. Metallic phases that contained aluminium, iron and titanium were gained during the alumothermic reduction of ilmenite. Titanium was successfully alloyed into the steel melt by introducing the alumothermic mixture into the melt, while the presence of titanium nitrides confirms that the titanium was reduced in the melt and reacted with the dissolved nitrogen"},{"@xml:lang":"sl","#text":"Izvedeni so bili poskusi alumotermične redukcije ilmenita. Ilmenit je mineral,ki vsebuje titanove in železove okside (FeO x TiO2). Rezultati so potrdili, da v jeklu poteče alumotermična redukcija. Produkti redukcije pa kažejo na to, da je reakcijski mehanizem bolj zapleten, kot pa zgolj nastajanje elementarnega titana, saj nastajajo različne kovinske faze. Izvedeni sta bili dve vrsti poskusov: alumotermična redukcija ilmenita in legiranje alumotermične mešanice v jekleno talino. Dobljen je bil vpogled v procese na fazni meji med jekleno talino, titanom in nastalimi kovinskimi fazami, preden se titan raztopi v jeklu. Ugotovljeno je bilo, da se titan raztaplja v jeklu prek nastanka intermetalnih faz. Produkti redukcije so bile kovinske faze, ki so vsebovale aluminij, titan in železo. Prisotnost titanovih nitridov v jeklu, ki smo ga legirali z mešanico, pa je dokaz, da je bil titan legiran v kovinski obliki, kjer je reagiral z raztopljenim dušikom"}],"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-A2BAFIL3","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-A2BAFIL3"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-A2BAFIL3/1097a663-a070-4f24-9f5a-88c19df38524/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-A2BAFIL3/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-A2BAFIL3"}}}}
