20.500.12556/DKUM-66578 Microstructure of NiTi orthodontic wires observations using transmission electron microscopy This work presents the results of the microstructure observation of six different types of NiTi orthodontic wires by using Transmission Electron Microscopy (TEM). Within these analyses the chemical compositions of each wire were observed in different places by applying the EDS detector. Namely, the chemical composition in the orthodontic wires is very important because it shows the dependence between the phase temperatures and mechanical properties. Micro- structure observations showed that orthodontic wires consist of nano-sized grains containing precipitates of Ti2Ni and/or TiC. The first precipitated Ti2Ni are rich in Ti, while the precipitated TiC is rich in C. Further investigation showed that there was a difference in average grain size in the NiTi matrix. The sizes of grains in orthodontic wires are in the range from approximately 50 to 160 nm and the sizes of precipitate are in the range from 0,3 μm to 5 μm. orthodontic wires nickel-titanium orthodontic wire NiTi wire shape memory alloys SMA wires microstructure transmission electron microscopy TEM average grain size orotodontske žice NiTi žice spominske zlitine mikrostruktura materiala preiskava materiala transmisijska elektronska mikroskopija true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-07-03 13:52:44 2017-07-03 13:53:39 2022-08-01 12:56:08 2019-07-11 15:52:05 2014 0 0 str. 469-472 št. 4 Letn. 53 2014 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1334-2576 620.187:669.245 524301593 17828374 1334-2576 URN:SI:UM:DK:O6HMP5SZ Metalurgija_2014_Fercec_et_al._Microstructure_of_NiTi_orthodontic_wires_observations_using_transmission_electron_microscopy.pdf Metalurgija_2014_Fercec_et_al._Microstructure_of_NiTi_orthodontic_wires_observations_using_transmission_electron_microscopy.pdf 1 B6DB6CD8DD41F932AAAFE1F056E8CADE 316ff8179629d8e670c2f717114aea15bbd57f98235681a5f06486a87cf57a8c 570a01e2-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/e3ba824d-ebfa-405c-94d2-3b488ea79348 https://dk.um.si/Dokument.php?lang=slv&id=113504 http://hrcak.srce.hr/122165 1 https://dk.um.si/Dokument.php?lang=slv&id=113503 Fakulteta za strojništvo 0 0 0
