The tests were performed in the temperature range 850-1150 °C and strain-rate range 0.001-10 ssup{-1}. With decreasing of the deformation temperature and increasing of the strain-rate values of the peak strain, the peak and steady-state stresses increase. The hyperbolic sine Arrhenius function was used to determine the apparent activation energy for the hot workability. The apparent activation energy of 356 kJ molsup{-1} for entire hot-working range was calculated using the peak stresses. The power-dissipation maps exhibited a single domain with the peak of efficiency in the range 30-40 %, the temperature range 960-1100 °C and a strain rate of 1.0 ssup{-1}</dc:description><dc:description xml:lang="sl">Raziskana je bila vroča preoblikovalnost orodnega jekla za delo v hladnem 95MnWCr5. Na termomehanskem simulatorju Gleeble 1500D so bili izvedeni tlačni preizkusi v temperaturnem območju 850-1150 °C in v območju hitrosti deformacije 0,001-10 sna{-1}. S padajočo temperaturo deformacije naraščajo vrednosti najvišjih deformacij in napetosti ter napetosti pri stabilnem stanju. Z uporabo sinushiperbolične Arrheniusove funkcije je bila izračunana navidezna aktivacijska energija za vroče preoblikovanje. Na celotnem temperaturnem področju ter za maksimume napetosti tečenja izračunana aktivacijska energija je 365 kJ molna{-1}. Na mapah učinkovitosti porazdelitve energije je le eno območje z največjim izkoristkom v območju 30-40 %, in sicer pri temperaturah v območju 960-1000 °C in hitrosti deformacije 1,0 sna{-1}</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-TJA4NU33"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-TJA4NU33" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-TJA4NU33/c78cea7a-c403-4319-927d-0dc92fe21eaf/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Inštitut za kovinske materiale in tehnologije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-TJA4NU33/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-TJA4NU33" /></ore:Aggregation></rdf:RDF>
