Pulsed Nd:YAG laser machining of nitinol: An experimental investigation

Journal of Micromanufacturing, 2021
Nickel–Titanium (Ni-Ti) shape memory alloy, commonly called nitinol alloys, finds its primary application in the production of biomedical implants, mainly because of itsrare properties such asshape memory, superelasticity and superior biocompatibility ...

Surface Modifications of Nitinol

Journal of Long-Term Effects of Medical Implants, 2009
Nitinol (an acronym for the Nickel-Titanium Naval Ordnance Laboratory) has been extensively explored as an implant material for the medical industry. The potential problem with Nitinol implant devices is the release of Ni in the human body, which has stimulated a great deal of research on surface modifications and the application of coatings.

Thermodynamics of Nitinol

Journal of Applied Physics, 1987
A self-consistent macroscopic thermodynamics is developed for the calculation of work, heat, and dissipation for thermodynamic paths of the shape memory alloy, Nitinol. The thermodynamic system analyzed is a Nitinol helix for which extensive force–length–temperature (FLT) equation of state measurements have been made.

Bending characteristics of nitinol wire

American Journal of Orthodontics, 1979
U ntil recently only a limited group of alloys have been used for orthodontic wires, namely, gold-caper, austenitic stainless steel, and chromium-cobalt-nickle (CrCo-Ni) based materials. In general, the last two groups have similar mechanical properties although processing, stress-relieving, heat-treating, and minor alloying adjustments allow for small

Nitinol in Magnetic Resonance Imaging

Minimally Invasive Therapy & Allied Technologies, 2004
Surgical and interventional instruments as well as implants can cause significant magnetic resonance image (MRI) artifacts. The artifacts can be used to visualize instruments, cannulae, guide wires, catheters during interventional MRI and Nitinol devices have proven to be useful for MRI procedures. Diagnostic imaging is often compromised in the area of

Fatigue Fracture of Nitinol

Journal of Failure Analysis and Prevention, 2021
Abstract Nitinol fatigue fracture surfaces generally exhibit similar features to most engineering alloys, including a flat fracture plane, ratchet marks, radial lines, beachmarks, and striations.

A review on Nitinol shape memory alloy heat engines

Smart materials and structures (Print), 2020
Nitinol (NiTi) shape memory alloy (SMA) heat engine is a very promising candidate application of SMA since its invention, but yet to be put as commercial due to its low efficiency and performance.

Effect of Bone Quality and Leg Depth on the Biomechanical Performance of a Nitinol Staple.

Journal of Foot and Ankle Surgery, 2021
The use of Nitinol compression staples has increased in foot and ankle procedures due to their ease of delivery and ability to offer sustained, dynamic compression. Prior biomechanical studies have predominantly examined mechanical performance in healthy
