The utility of superelasticity in medicine
Bio-Medical Materials and Engineering, 1996Nitinol alloys (Nitinol) exhibit a dramatically enhanced elasticity, known as “superelasticity”, which is becoming integral to the design of a variety of new medical products. Elasticity is the most apparent of the advantages afforded by this material, but by no means the only or most important.

AbstractSuperelastic materials (crystal‐to‐crystal transformation pseudo elasticity) that consist of organic components have not been observed since superelasticity was discovered in a Au‐Cd alloy in 1932. Superelastic materials have been exclusively developed in metallic or inorganic covalent solids, as represented by Ti‐Ni alloys ...

“Giant Superelasticity Effect” in NiTi Superelastic Materials and Its Applications
Journal of Materials in Civil Engineering, 2006Nitinol superelastic materials (SEM) are mostly used for low-force/large displacements applications involving tensile or bending modes of loading. The paper describes experiments on the radial compression of superelastic wires and tubes between flat loading surfaces. Elastic (recoverable) deformations—up to 22.5% with high damping under loads in the kN/

Superelastic electron scattering on lithium
Physical Review A, 1996Reduced Stokes parameters of the 2{sup 2}{ital P} state of lithium are measured using superelastic electron-scattering techniques and calculated using the convergent close-coupling method. The measurements and calculations are in excellent agreement at all scattering angles.

An overview of superelastic stent design
Minimally Invasive Therapy & Allied Technologies, 2000The purpose of this paper is to contrast the performance of self-expanding and balloon-expandable stents. While both approaches to stenting have proven to be successful in treating a wide range of vascular disease, there are significant differences in the philosophy behind and properties of the two types of stents.

Bending of Beams in Superelasticity Domain
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2000AbstractThe paper deals with bending of beams made of shape memory material (SMM). The research is focused on the modelling of a bending process in the superelasticity region, which w one of the characteristics of SMM. On the basis of a chosen physical model, a computer program has been set up for numerical modelling of the stress‐strain and ...

Network Modulus and Superelasticity
Macromolecules, 1994We discuss the elastic modulus G and swelling/deswelling behavior of networks as a function of their concentration 4 and their preparation state. Simple scaling ideas reproduce the prediction of James and Guth for the modulus of networks swollen in a 8 solvent (G - 4113) but lead to a new prediction in a good solvent (G - 4'/12).

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.

Superelastic Polymer Aerogel with Superamphiphilicity
ACS Applied Materials & InterfacesElastic aerogels have become a research hot spot in both academia and industry recently. The reported elastic aerogels are all made of hard materials by controlling their shapes. Herein we report an elastic aerogel made of a polymer elastomer with entropy elasticity. In the aerogel, cross-linked carboxyl nitrile rubber nanoparticles with hydrophilicity

Superelastic Hard Carbon Nanofiber Aerogels
Advanced Materials, 2019AbstractSuperelastic carbon aerogels have been widely explored by graphitic carbons and soft carbons. These soft aerogels usually have delicate microstructures with good fatigue resistance but ultralow strength. Hard carbon aerogels show great advantages in mechanical strength and structural stability due to the sp3‐C‐induced turbostratic “house‐of ...
