Pseudoelasticity in Fe3Ga single crystals

Scripta Materialia, 2005
Abstract We first found pseudoelasticity in Fe 3 Ga single crystals regardless of a thermoelastic martensitic transformation. Superpartial dislocations with Burgers vector of 1/4[1 1 1] were pulled back by nearest-neighbour and next-nearest-neighbour antiphase boundaries during unloading, resulting in the pseudoelasticity.

Controllable Pseudoelasticity in Metallic Nanocrystals by Grain Boundary Engineering.

Nano letters (Print)
Materials with pseudoelasticity can recover from large strains exceeding their elastic limits during unloading, making them promising damage-tolerant building blocks for advanced nanodevices.

Twinning pseudoelasticity in InTl

Acta Metallurgica, 1983
Abstract Twin boundaries generally contribute significantly to the damping of a twinned crystal. In an In-19.1 at.% Tl single crystal the damping gives rise to automodulation if the internal friction studies are performed in the 10 Hz frequency range, with a strain amplitude larger than 0.05 and at temperatures lower than 10°C.

Shape Memory and Pseudoelasticity in Metal Nanowires

Physical Review Letters, 2005
Structural reorientations in metallic fcc nanowires are controlled by a combination of size, thermal energy, and the type of defects formed during inelastic deformation. By utilizing atomistic simulations, we show that certain fcc nanowires can exhibit both shape memory and pseudoelastic behavior. We also show that the formation of defect-free twins, a

Non-isothermal oscillations of pseudoelastic devices

International Journal of Non-Linear Mechanics, 2003
Abstract The non-linear dynamic response of a pseudoelastic oscillator embedded in a convective environment is studied taking into account the temperature variations induced, during oscillations, by the latent heat of transformation and by the heat exchange with the surroundings.

Pseudoelastic NiTi‐Alloys under Cyclic Loading

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2000
AbstractIn addition to the shape memory effect, shape memory alloys show two further properties that are useful for mechanical applications: pseudoelasticity and a very high damping capacity compared to other metals. Beside the temperature both characteristics depend on the amplitude and rate of the mechanical load, as well as on the load history.

Pseudoelasticity and Shape Memory

1986
Alloys with shape memory are characterized by a strong dependence of the load-deformation behaviour upon temperature. At low temperatures they behave much like plastic bodies with initial elastic deformation, yield and residual deformation after unloading, but at higher temperatures they exhibit pseudoelastic behaviour, i.e.

Compressive pseudoelastic behavior in copper nanowires

Physical Review B, 2010
We predict the pseudoelasticity of the $⟨100⟩/{100}$ copper nanowire using atomistic simulations with the embedded atom method potential under uniaxial compressive loading. The $⟨100⟩/{100}$ copper nanowire exhibits pseudoelasticity which depends on the reorientation of the crystalline structure of the nanowire due to twinning.
