Influence of Nitrogen Ion Implantation on Deformation and Fatigue Properties of TiNi Shape-Memory Alloy Wire

Archives of Mechanics, 2013
A shape memory alloy (SMA) is expected to be applied as intelligent material since it shows the unique characteristics of the shape memory effect and superelasticity. Most SMA elements, with these characteristics, perform cyclic motions.

Deformation mechanisms in a TiNi shape memory alloy during cyclic loading [PDF]

, 2012
The deformation mechanisms governing the cyclic stress-strain behaviour of a TiNi shape memory alloy were investigated in this work. To understand the development of these mechanisms during cyclic loading, three low-cycle fatigue tests were performed and

Superelastic NiTi scaffolds with extensively tuneable mechanical and mass transfer properties

International Journal of Extreme Manufacturing
Natural bones exhibit a substantial recoverable strain ( ϵ _rec ) of 2%‒4% and vary in mechanical and mass transfer properties across different body regions.

Low-alloy content Ti-Mo-based alloys with large superelasticity and narrow stress hysteresis for potential biomedical applications

Materials Research Letters
In most Ni-free Ti-Nb- and Ti-Zr-based superelastic alloys, large amounts of high-cost and rare elements such as Nb, Ta, Hf and/or Zr are contained, increasing the cost and fabrication difficulty of the alloy.

Effect of the heat treatment on martensitic transformations in single crystals of iron-based alloy [PDF]

, 2017
The shape memory effect, superelasticity and temperature range of superelasticity were investigated on [001]-oriented single crystal of FeNiCoAl(Ti+Nb+Ta) alloy, aged at temperature of T=973 K for 0,5, 3 and 5 h.

Orthodontic Open-Coil Spring Deactivation Forces Differ with Varying Activation Levels [PDF]

, 2018
Coil springs are used in orthodontics to deliver forces to move teeth. However, the optimal amount of activation to produce predictable, continuous deactivation forces, for the purpose of orthodontic tooth movement, is unclear.

Correlation between Local Structure Distortions and Martensitic Transformation in Ni-Mn-In alloys

, 2010
The local structural distortions arising as a consequence of increasing Mn content in Ni_2Mn_1+xIn_1-x (x=0, 0.3, 0.4, 0.5 and 0.6) and its effect on martensitic transformation have been studied using Extended X-ray Absorption Fine Structure (EXAFS ...

Numerical Simulation and Experimental Study of a Simplified Force-Displacement Relationship in Superelastic SMA Helical Springs

Sensors, 2018
This paper proposes a new force-displacement model for superelastic shape memory alloy (SMA) springs under complex loading and unloading. For the SMA wires used to make superelastic springs, a new multilinear constitutive model based on a modification of
