Pseudoelasticity at Large Strains in Au Nanocrystals [PDF]

Physical Review Letters, 2018
Pseudoelasticity in metals is typically associated with phase transformations (e.g., shape memory alloys) but has recently been observed in sub-10 nm Ag nanocrystals that rapidly recovered their original shape after deformation to large strains. The discovery of pseudoelasticity in nanoscale metals dramatically changes the current understanding of the ...

Pseudoelasticity of SrNi2P2 Micropillar via Double Lattice Collapse and Expansion [PDF]

, 2021
The maximum recoverable strain of most crystalline solids is less than 1% because plastic deformation or fracture usually occurs at a small strain.

Abnormal grain growth of FeMnAlNiCo shape memory alloys during directional recrystallisation

Journal of Materials Research and Technology, 2023
Polycrystalline FeMnAlNi-based alloys generally exhibit poor pseudoelasticity owing to grain constraint. A promising method to improve the pseudoelasticity involves increasing the grain size by directional recrystallisation (DR).

Effect of cold-drawn-induced amorphous phase on microstructure and pseudoelasticity properties of nanocrystalline NiTi alloys

Journal of Materials Research and Technology, 2023
Amorphous structures can be induced by cold deformation in the NiTi shape-memory alloys, which transform into nanocrystalline structures after annealing.

Applications of Shape Memory Alloys for Neurology and Neuromuscular Rehabilitation

Journal of Functional Biomaterials, 2015
Shape memory alloys (SMAs) are a very promising class of metallic materials that display interesting nonlinear properties, such as pseudoelasticity (PE), shape memory effect (SME) and damping capacity, due to high mechanical hysteresis and internal ...

Large Deformation Constitutive Theory for a Two-Phase Shape Memory Alloy

Engineering Transactions, 2015
In this work we examine significant theoretical issues related to the constitutive modelling of a two-phase shape memory alloy which undergoes large deformations. For this purpose, we propose a new generalized plasticity based model.
