Consequently the new group of steel grades exhitis very rapid bainite formation at low temperatures, commonly below 250°C. These steels develop a very fine bainitic microstructure during continuous cooling/quenching from the austenitization temperature, without the need for isothermal heat treatments. Impact toughness and other mechanical properties meanwhile remain in compliance with common standard specifications, while also retaining sufficient hardenability to ensure homogeneous properties throughout thick sections. These steels develop a hardness of up to 65HRC and a low distortion during heat treatment. This combination of mechanical properties makes such steels particularly suitable for the production of tools, rolls, knives, ballistic protection and machine parts requiring high strength.The major trait in these steels is the formation of bainite nuclei at high temperatures and the subsequent growth of bainitic ferrite at lower temperatures. Tis is in contrast with contemporary data on standardized steels where these two process are thought to occur simultaneously. The method by which this is achieved is termed Kinetically activated bainite KAB, and the group of alloys KAB steels"},{"@xml:lang":"sl","#text":"V okviru doktorske disertacije je bil razvit nov postopek hitre tvorbe bainita v jeklih ter posledično nova skupina bainitnih jekel, ki imajo izjemno hitro kinetiko tvorbe bainita pri nizkih temperaturah, običajno pod 250°C. Za ta jekla je značilen razvoj izjemno fine bainitne mikrostrukture med kontinuirnim ohlajanjem/kaljenjem iz temperature avstenitizacije, ne da bi pri tem potrebovali izotermne toplotne obdelave. Udarna žilavost in druge mehanske lastnosti ostajajo v skladu z najpogostejšimi zahtevami glede žilavosti in standardnimi specifikacijami, hkrati pa ohranjajo zadostno prekaljivost za zagotovitev homogenih lastnosti znotraj velikih presekov. Ta jekla imajo visoko trdoto do 65HRC in majhno geometrijsko popačenje oz. distorzijo med toplotno obdelavo.Zaradi teh lastnosti so novo razvita jekla še posebej primerna za izdelavo orodij za delo v hladnem, nožev, balistične zaščite ter strojnih delov visoke trdnosti. Ključna značilnost teh jekel je tvorba bainitnih nukleusov pri visoki temperaturi in hitra rast bainitnega ferita pri nizki temperaturi. To je v nasprotju z običajnimi oz. splošno poznanimi jekli in železovimi zlitinami, znotraj katerih se ta dva koraka izvajata sočasno. Metoda, s katero smo to dosegli, se je poimenovala kinetična aktivacija bainita -KAB in skupine zlitin KAB jekla"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"visokošolska dela"},{"@xml:lang":"en","#text":"theses and dissertations"},{"@rdf:resource":"http://www.wikidata.org/entity/Q1266946"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-GDO86VXO","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-GDO86VXO"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-GDO86VXO/5f5dae3-dd9e5b6334a36996-581d-b69-3c/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":"Univerza v Mariboru, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-GDO86VXO/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-GDO86VXO"}}}}
