20.500.12556/DKUM-26540 Metallographic sample preparation of orthodontic Ni-Ti wire Shape memory alloys (SMA) has been at the forefront of research for the last several decades. In this field especially, Nickel-Titanium (Ni-Ti) alloys have been found to be the most useful of all SMA. The most important applications of SMA Ni-Ti alloys are namely in medicine and dentistry, where they are used as orthodontic wires. In this paper we describe the procedure of preparing metallographic samples of typical orthodontic Ni-Ti wires which are nowadays used in dentistry praxis. We prepared the samples for microstructure observation using a light microscope. Special attention is given to the metallographic preparation, which could result in damages and deformations of the sample surfaces if the procedure is incorrect. Finally, we illustrated the typical metallographic recipe for Ni-Ti SMA alloys for optical observation. shape memory alloys Ni-Ti wire metallographic preparation microstructure true false false Angleški jezik Angleški jezik Neznano 2012-05-31 13:58:34 2012-05-31 13:58:34 2022-04-15 03:41:59 2024-01-03 03:31:11 2009 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 669.245'295:621.315.554]:620.18 13873686 0354-6306 URN:SI:UM:DK:Q9LBF7Y3 http://www.metalurgija.org.rs/mjom/vol15/No%204/6_Zorko_MJoM_1504.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=35590 Fakulteta za strojništvo 0 0 0
