Nitinol Strain Effects

JOM, 1987
Straining annealed Nitinol (TiNi) wire changes the characteristics of its subsequent phase transformation. It generates peaks in electrical resistance and an additional peak in the calorimetry curve. This work explores the relationship between the stress associated with this strain and the peaks formed during transformation.

Biocompatibility of Nitinol

Minimally Invasive Therapy & Allied Technologies, 2000
This review links together recent information on the biocompatibility of Nitinol. Fundamental aspects of biological responses to Nitinol and its alloy components are clarified. The clinical advantages of using this functional biomaterial are evident. Although most studies support the good biocompatibility of Nitinol, there are still a lot of unanswered

Corrosion resistance of a Nitinol ocular microstent: Implications on biocompatibility.

Journal of Biomedical Materials Research. Part B - Applied biomaterials, 2020
Nitinol is commonly used in medical implants due to its unique thermomechanical properties of shape memory and superelasticity. Free nickel has the potential to induce biological responses that may be a concern for permanent implants manufactured from ...

Metallographic method for nitinol

Metallography, 1985
Abstract It is demonstrated that for the alloy Ni-Ti, mechanical polishing followed by electrolytic polishing using a jet polisher such as the Struers Tenupol produces areas suitable for microscopical examination of the structure with polarized light illumination.

Optimization of laser parameters for improved corrosion resistance of nitinol

, 2020
Nickel-Titanium (Nitinol) alloy is one of the shape memory alloys with potential applications in biomedical and aerospace industries. However, long-term deployment of nitinol-based alloys in fluid medium leads to corrosion.

Nitinol Stents in Hemodialysis Access

Journal of Vascular and Interventional Radiology, 2004
MAINTAINING permanent vascular access remains the Achilles heel of hemodialysis. In the era of widespread use of percutaneous angioplasty and thrombectomy for salvaging failing and failed hemodialysis accesses, the consensus guidelines of the National Kidney Foundation Dialysis Outcomes Quality Initiative recommend relatively modest benchmarks: a 50% 6-

Nitinol Surfaces for Implantation

Journal of Materials Engineering and Performance, 2009
Nitinol, a group of nearly equiatomic Ni-Ti alloys, steadily conquers new areas of application. Because of the need to keep a low profile of miniature implant devices, and considering the lack of compatibility between Nitinol superelasticity and the mechanical properties of traditional coatings, bare surfaces are of interest.

Martensitic transformation in nitinol

Metallography, 1985
Abstract Optical metallographic evidence is presented for the formation of martensite, and reversion of the martensite to the β phase in nitinol during thermal cycling and during shape memory behavior.
