Hot-rolling was conducted at 1050 °C in a two-phase field of the alloy. Strain-rate jump tests were performed at T = 800-1100 °C and strain rates of 10-6 to 10-3 s-1. Creep stress exponent (n) and activation energy for deformation (Q) were used to identify deformation mechanisms. Two sequential mechanisms are revealed: (i) viscous glide, typical of solid solution alloys and, (ii) power law breakdown at lower temperatures. Activation energy for deformation was found to be strongly stress-dependant</dc:description><dc:description xml:lang="sl">Zlitina Ti3Al-11Nb-1V (x/%) je bila izdelana v vakuumski obločni peči. Vroče valjanje je bilo opravljeno pri 1050 °C v dvofaznem območju zlitine. Sunkoviti preizkusi hitrosti deformacije so bili narejeni pri T = 800-1100 °C in pri hitrosti deformacije 10-6 to 10-3 s-1. Eksponent napetosti lezenja (n) in aktivacijska energija deformacije (Q) sta bila uporabljena za identifikacijo mehanizma deformacije. Odkrita sta bila dva sekvenčna mehanizma: (i) viskozno drsenje, ki je značilno za zlitine iz trdnih raztopin in (ii) prelom potenčnega zakona pri nižji temperaturi. Ugotovljeno je bilo, da je aktivacijska energija deformacije zelo odvisna od napetosti</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-XUPFD1K2"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-XUPFD1K2" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-XUPFD1K2/44e51195-edf5-46e6-975d-28b66d9091a0/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-XUPFD1K2/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-XUPFD1K2" /></ore:Aggregation></rdf:RDF>
