“…The EDS analysis was used for quantitative elemental analysis, but LIBS' advantage is that the archwirеs can be analyzed in depth. It has been proven that the LIBS analysis can be used for the qualitative characterization of such samples and the results from this research contributed to the overall explanation of the properties of the Bio-active™ orthodontic archwires [13].…”

“…The amounts of Ni and Ti are approximately 55 wt.% and 45 wt.%, respectively. This corresponds to the multi-force TriTanium TM orthodontic archwire elemental composition ratio, whose Ni and Ti content are about 54 wt.% and 46 wt.% [13]. Different amounts of Fe and Cr were registered in the various areas with differential force release.…”

“…The austenite structure was maintained during the orthodontic treatment in the three regions of the clinically retrieved Bio-active™ archwires. The XRD pattern of the Bio-active™ archwires is similar to the XRD pattern of the TriTanium™ archwire and the heat-activated Ni-Ti archwires, and their peaks are at the same 2θ degrees [11][12][13]. The similarity between the abovementioned archwires is expected because they are all made from Ni-Ti alloy.…”

This study aimed to characterize and compare the latest generation multi-force Bio-active™ orthodontic archwires to determine if there is a change in their physicochemical and mechanical properties during orthodontic treatment. The physicochemical characterization of the archwires was done by X-ray diffraction (XRD), scanning electron microscopy, energy-dispersive X-ray spectroscopy and laser-induced breakdown spectroscopy. A modified dynamic nanoindentation method with depth control was used to determine the mechanical properties. Statistical analysis was done by one-way analysis of variance (ANOVA). The XRD analysis showed that all investigated archwires are made of Ni-Ti alloy with an austenite crystal structure. The surface roughness of the Bio-active™ wires decreases after clinical use. The elemental composition analysis showed that the weight percentage of nickel and titanium is approximately 55 wt.% and 45 wt.%, respectively, and traces of Fe and Cr were registered in some regions. The results from nanoindentation experiments showed that the indentation hardness in the bicuspid part of archwires used for six weeks decreases by about 154%, and the indentation modulus decreases by about 44% compared to as received archwires, probably due to the changes in the morphology. Statistically significant differences in the chemical content are found for the anterior and bicuspid regions, while in the mechanical properties, for the bicuspid and posterior regions of the investigated archwires. The obtained results give orthodontists important information about the physicochemical and mechanical properties of the Bio-active™ multi-force archwires during their clinical use.

This work presents the results of the electron-beam welding of commercially pure α-Ti (CP-Ti) and Ti6Al4V (Ti64) alloys. The structure and mechanical properties of the formed welded joints were examined as a function of the power of the electron beam. The beam power was set to P1 = 2100 W, P2 = 1500 W, and P3 = 900 W, respectively. X-ray diffraction (XRD) experiments were performed in order to investigate the phase composition of the fabricated welded joints. The microstructure was examined by both optical microscopy, scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDX). The mechanical properties of the formed joints were studied using tensile test experiments and microhardness experiments. The results of the experiments were discussed concerning the influence of the beam power on the microstructure and the mechanical properties of the weld joints. Furthermore, the practical applicability of the present method for the welding of α-Ti and Ti64 was also discussed.
