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

open access: yesArchives 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.

Torsion and Bending Properties of EdgeEndo Files [PDF]

open access: yes, 2016
Introduction: One important step of root canal therapy is the process of cleaning and shaping each canal. This process involves using endodontic rotary files combined with chemical irrigants to remove pulpal remnants and infected dentin from the canal ...

Superelasticity and its cyclic stability in [001]-oriented single crystals and oligocrystals of FeMnAlNi alloy in compression

open access: yesLetters on Materials, 2020
Superelasticity and stability of superelasticity in isothermal loading / unloading cycles under compression up to 3.5 – 4 % at room temperature were studied in [001]-oriented Fe 43.5 Mn 34 Al 15 Ni 7.5 (at.%) single crystals and Fe 42.5 Mn 34 Al 15 Ni 7 ...

Finite Size‐Effects in Martensite Microstructure of Magnetic Shape Memory Films

open access: yesSmall, EarlyView.
Magnetic shape memory alloys are a promising multifunctional material system for integration into microsystems. Their multifunctionality arises from the coexistence of ferroelasticity and ferromagnetism. While size‐effects in ferromagnetic microstructure are well understood, corresponding experiments on the ferroelastic microstructure are sparse.

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

open access: yesMaterials 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.

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

open access: yes, 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
