Abstract:The aim of this paper was to analyse the characteristic properties of six different, commercially available nickel-titaniumorthodontic wires with a diameter of 0.305 mm (0.014"). The characteristic properties were determined by usingsemi-quantitative EDX analyses, DSC analyses for a determination of the phase temperatures, and a tensile test to obtain themechanical properties of the wires. The investigation of the chemical composition showed an equiatomic NiTi alloy. Analysesof phase temperatures showed that the nickel-titanium orthodontic wires were, in an austenitic microstructure, exhibiting asuperelastic effect in the oral environment. The uniaxial tensile stressstrain curves showed different values for the beginningand the end of the transformation range during the loading.

Title:Primerjava ortodontskih lokastih žic NiTi in določitev značilnih lastnosti
Abstract:Prispevek obravnava analizo karakterističnih lastnosti 6 komercialno dostopnih nikelj titanovih ortodontskih žic, ki imajo premer 0,305 mm (0,014") v fazi pred njihovo uporabo v ustih. V teh okvirih so bile analizirane mehanske lastnosti z enoosnim nateznim preizkusom, za določitev faznih temperatur pa je bila izvedena DSC-analiza ter semikvantitativna EDX-analiza. Dobljene enoosne krivulje napetost raztezek so pokazale različne vrednosti začetka in konca transformacijskega območja pri obremenjevanju NiTi-žic. Analiza faznih temperatur je potrdila, da imajo ortodontske žice avstenitno mikrostrukturo, s čimer kažejo superelastični efekt, potem ko so v uporabi v ustnem okolju. Krivulja napetost-raztezek pri enoosnem nategu je pokazala različne vrednosti za začetek in konec transformacijskega območja med obremenjevanjem.
Keywords:nikljeve zlitine, titanove zlitine, zlitina s spominom oblike, fazna transformacija, termična analiza, natezni preizkus
