The specimens for the three point bending tests and fracture toughness test were austenitized at two different temperatures, quenched with or without the sub-zero treatment and then double tempered. The bending strength was lower by higher austenitizing temperature and also with the use of sub-zero treatment. The average fracture toughness was lower by higher austenitizing temperature also and increased slightly with the sub-zero treatment. The lowering of bending strength can be considered as logical result because of the austenitic grain growth, as well as increased internal stresses in the case of sub-zero processed samples. For fracture toughness, the situation seems to be more complex. On one side, the effect of austenitizing temperature on fracture toughness is similar as for bending strength, on the other side, the sub-zero treatment induces a rather slight increase of fracture toughness. The paper presents some details on the experiments performed including possible explanation of the material's behaviour considering microstructure investigations"},{"@xml:lang":"sl","#text":"PM-jeklo Vanadis 6 je zelo popularno orodno jeklo za različno uporabo v hladnem. Preizkušance za tri točkovni upogib in žilavost loma smo avstenitizirali pri dveh različnih temperaturah, kalili z obdelavo in brez nje pod temperaturno ničlo in dvakrat popustili. Ugotovili smo, da je upogibna trdnost nižja po kaljenju z višje temperature in po obdelavi pod ničlo. Žilavost loma je bila nižja po kaljenju z višje temperature in je bila nekoliko večja po obdelavi pod ničlo. Zmanjšana upogibna trdnost je logičen rezultat povečanja velikosti avstenitnih zrn in povečanja notranjih napetosti po obdelavi pod ničlo. Primer žilavosti loma je bolj kompleksen, kajti na eni strani temperatura avstenitizacije vpliva podobno na upogibno trdnost in žilavost loma, po drugi pa obdelava pod ničlo poveča žilavost loma.V članku so predstavljeni detajli o opravljenih preizkusih in predstavljena je razlaga vedenja materiala z upoštevanjem mikrostrukture"}],"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-OVYZQUY9","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-OVYZQUY9"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-OVYZQUY9/1a02a973-f750-4c22-980f-51927fd602c5/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-OVYZQUY9/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-OVYZQUY9"}}}}
