WebAug 8, 2016 · Three kinds of NiTiNb shape memory alloys, which possess a nominal chemical composition of Ni 50−x/2-Ti 50−x/2-Nb x (at.%) where x stands for 2, 4 and 6, respectively, were designed in order to investigate the influence of the addition of Nb on phase transformation, microstructure and mechanical properties of equiatomic NiTi … There are four commonly used types of applications for nitinol: Free recovery Nitinol is deformed at a low temperature, and heated to recover its original shape through the Shape Memory effect. Constrained recovery As for free recovery, except that recovery is rigidly prevented and thus a stress is generated. Work production Here the alloy is allowed to recover, but to do so it …

WebJul 1, 2024 · Abstract. In the present work, the effects of laser surfacing aiming at modifying the surface roughness on NiTi sheets prior to the application of ultrasonic welding (USW) were investigated. Three different configurations joining original and laser surfaced specimens were performed: original/original (referred as O/O), original/treated (referred as … WebBroken instruments are a serious obstacle to shaping, cleaning, and filling of the root canal and can adversely affect the outcome of endodontic therapy. The aim of this study was to examine the magnetic properties and ultrastructural changes of new, used, and fractured NiTi instruments using opto-magnetic imaging spectroscopy (OMIS).
