The effect of these sintering parameters on the densification, microstructure, hardness and tensile properties of the niobium-modified, heat-resistant stainless steel GX40CrNiSi25-20 were investigated. The prepared feedstock was injection molded to obtain tensile test specimens (ISO 2740). The debinding of the molded parts was performed using the catalytic debinding method, while the residual binder was removed by thermal debinding. The sintering was performed at 1200 °C and 1310 °C, in argon (Ar), hydrogen (H2) and nitrogen (N2) atmospheres, with the sintering times between 3 h and 6h. It was found that sintering in a nitrogen atmosphere increased the strength and reduced the ductility. The mechanical properties were also enhanced by a higher sintering temperature (1310 °C), due to the positive effects of the pore rounding and increased density. The prolonged sintering time caused changes in the grain size, but had little effect on the density. Faster sintering and improved ductility was observed for the samples sintered in hydrogen and argon atmospheres"},{"@xml:lang":"sl","#text":"Lastnosti izdelkov iz ognjevzdržnega nerjavnega jekla, izdelanih s tehnologij obrizganja praškastih materialov (MIM) so v največji meri odvisne od parametrov sintranja. Vplivi parametrov sintranja na zgoščevanje, mikrostrukturo, trdoto in trdnostne lastnosti z niobijem legiranega nerjavnega ognjevzdržnega jekla GX40CrNiSi25-20 so opisani v tem članku. Iz pripravljenega surovega materiala so bili nabrizgani vzorci za preizkuse z injekcijskim ulivanjem. Sintranje je bilo izvedeno pri temperaturah 1200 °C in 1310 °C v argonski (Ar), vodikovi (H2) in dušikovi (N2) atmosferi v trajanju med 3 h in 6 h. Ugotovljeno je bilo, da sintranje v dušikovi atmosferi povzroči utrjevanje materiala in zmanjšanje duktilnosti. Mehanske lastnosti so bile povečane tudi pri višji temperaturi sintranja (1310 °C) zaradi zaokroževanja por in povečanja gostote. Podaljšan čas sintranja je povzročil spremembe v velikosti zrn, vendar je imel majhen vpliv na gostoto sintranih delov. Hitrejše sintranje in izboljšana plastičnost je bila pri vzorcih, ki so bili sintrani v vodikovi in argonski atmosferi"}],"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-LUCJJW1U","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-LUCJJW1U"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-LUCJJW1U/68e9b5d9-8b5a-47e2-83e6-1673f76775e8/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-LUCJJW1U/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-LUCJJW1U"}}}}
