“…[12][13][14][15][16][17][18] The characteristic transformation temperatures for the austenite-to-martensite phase transformation as well as the mechanical response can be modified to meet application requirements through (i) thermo-mechanical processing, [19][20][21] (ii) slight variation from the equi-atomic NiTi chemical composition, [22,23] or (iii) addition of alloying elements. [24][25][26][27][28] This phase transformation generally involves an austenitic cubic B2 structure transforming to and from either a martensitic monoclinic B19 or orthorhombic B19¢ structure.…”

Shape memory alloys (SMAs) exhibit high damping capacity in both austenitic and martensitic phases, due to either a stress-induced martensite phase transformation or a stress-induced martensite variant reorientation, making them ideal candidates for vibration suppression devices to protect structural components from damage due to external forces. In this study, both quasi-static and dynamic compression was conducted on a martensitic NiTi SMA using a mechanical loading frame and on a Kolsky compression bar, respectively, to examine the relationship between microstructure and phase transformation characteristics of martensitic NiTi SMAs. Both endothermic and exothermic peaks disappear completely after experiencing deformation at a strain rate of 10 3 s À1 and to a strain of about 10 pct. The phase transformation peaks reappear after the deformed specimens were annealed at 873 K (600°C) for 30 minutes. As compared to samples from quasi-static loading, where a large amount of twinning is observed with a small amount of grain distortion and fracture, samples from dynamic loading show much less twinning with a larger amount of grain distortion and fracture.

“…In the present study, we use plasma immersion ion implantation (PIII) to modify the surface characteristics of Ti substrates. PIII is a plasma-based ion implantation technique without line-of-sight limitations, the absence of which effectively improves the surface properties of Ti implants without altering cultured cell morphologies and without cell adhesion difficulties [17][18][19]. The implanted zone results from ion disruptions formed from an integrated part of the material, thus avoiding the risk of delamination associated with coating techniques.…”

“…With oxygen PIII treatment, the surface thickness of Ti oxides (mainly as TiO 2 ) on Ti substrates increased, resulting in improved corrosion resistance and cell adhesion [21][22][23][24]. Furthermore, the osseointegration of Ti implants was also improved [17,25]. However, the response of human osteoblast-like MG-63 cells to oxygen PIII (OPIII)-treated Ti substrates has not yet been determined.…”

In the present study, a nanoporous, biocompatible titanium dioxide (TiO 2 ) film was formed on the surface of titanium, using oxygen plasma immersion ion implantation (OPIII), and the influence of this film on the bio-functionalization, including the proliferation and differentiation properties of MG-63 osteoblast-like cells, was analyzed and investigated. The OPIII-treated surface was characterized by X-ray photoelectron, which showed that a TiO x layer was formed on Ti substrates. This TiO x surface exhibited nanoscale surface roughness in the form of nanoporous structures. The results also revealed that MG-63 cells expressed increased proliferation on the OPIII-treated surface as compared with the untreated Ti substrate. The Ti specimens treated with plasma energy of 1 kW revealed better expression of alkaline phosphatase (ALP) activity and showed higher average surface roughness than untreated specimens. Thus, it can be concluded that bioactivity of Ti implants can potentially be improved by OPIII.
