Namely, the NiTi alloy showed above the temperature where the fully austenitic phase behaviour has superelasticity. Superelastic behaviour is a property of the material and means that the material during the loading at a given stress causes the diffusion-less phase transformation from austenite to martensite. In doing so, a small rise in stress in the material causes changed elongation. The value for the beginning of transformation in the Shape Memory Alloy NiTi is highly dependent on the method of loading. Under tensile and compressive loading, asymmetrical stress occurs. In the present work we showed experimentally determined stress for the start of the transformation at tension loading and the theoretical calculation of the stress to start the transformation for compressive and shear loading</dc:description><dc:description xml:lang="sl">Za nikelj - titanove (NiTi) zlitine s spominom oblike je značilno posebno termo-mehansko vedenje. Zlitine NiTi kažejo nad temperaturo, kjer imajo popolno avstenitno fazo, superelastično vedenje. Superelatično vedenje je lastnost materiala in pomeni, da pride v materialu med obremenjevanjem pri določeni napetosti do brez-difuzijske fazne transformacije iz avstenita v martenzit. Pri tem se v materialu izredno spremeni raztezek ob relativno majhnem naraščanju napetosti. Vrednost začetka transformacije v zlitini s spominom oblike NiTi je izredno odvisna od načina obremenitve. Pri natezni in tlačni obremenitvi pride do asimetrije. V predstavljenem delu je prikazana eksperimentalno določena napetost za potek transformacije pri obremenitvi na nateg in teoretični izračun napetosti za začetek transformacije pri tlačni in strižni obremenitvi</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-1X45YJH6"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-1X45YJH6" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-1X45YJH6/6faddb37-75fd-4dcb-b889-815005508bf7/PDF" /><edm:rights rdf:resource="http://creativecommons.org/licenses/by-nc-nd/4.0/" /><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">Združenje Pomurska akademsko znanstvena unija</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-1X45YJH6/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-1X45YJH6" /></ore:Aggregation></rdf:RDF>
