The structure of porous nickel titanium reinforced by monolithic nickel titanium
Technical Physics Letters, 2006The structure and elemental composition of a composite representing porous nickel titanium reinforced by a monolithic nickel titanium rod (TN-10 alloy) have been studied. The structures of the initial TiNi powder (PN55T45S grade), the porous and monolithic parts of this composite, and the transition regions between these parts have been studied using a

Superelastic Nickel-titanium Wires
British Journal of Orthodontics, 1992Superelastic nickel-titanium archwires, unlike conventional wires, are capable of withstanding very large deflections and on returning to their original shape on deactivation will produce more moderate forces. The region over which there is a 'plateau' depends on the deflection and is greater the larger the deflection.

Electrochemical and surface characterization of a nickel–titanium alloy
Biomaterials, 1998For clinical implantation purposes of shape memory metals the nearly equiatomic nickel-titanium (NiTi) alloy is generally used. In this study, the corrosion properties and surface characteristics of this alloy were investigated and compared with two reference controls, AISI 316 LVM stainless steel and Ti6A14V.

Nickel–titanium: options and challenges
Dental Clinics of North America, 2004The introduction of nickel-titanium (NiTi) as material for endodontic instruments about 15 years ago opened many new perspectives. Many dentists and scientists see a benefit in using NiFi files. Initial problems such as frequent fractures and the uncertainty of the best way to use them have been solved.

Effect of surface treatment on the bioactivity of nickel–titanium
Acta Biomaterialia, 2008In this paper, the bioactive properties of Ni-Ti alloy after different surface treatments were evaluated in different media (Hanks' balanced salt solution, Dulbecco's modified Eagle's medium and osteogenic). Evaluation was performed on the basis of X-ray photoelectron spectroscopy and atomic force microscopy studies after immersing samples for up to ...

Applications of Nickel-Titanium Alloy
Journal of Engineering and Technology, 2015Nitinol exists in equiatomic phase of nickel-titanium (Ni-Ti). Nitinol has various applications in biomedical, automotive actuators, micro-electromechanical systems (MEMSs) and aero-space industries due to its distinctive properties of pseudo-elasticity, bio-compatibility, corrosion resistance and shape memory effect.

This study measured displacement of canal centers in extracted human teeth after preparation by Lightspeed and nickel-titanium K-files. The specimens were divided into two groups (n = 11), after radiographing the roots from the buccolingual and mesiodistal planes with pathfinding files in situ.
