Local chemical inhomogeneity enables superior strength-ductility-superelasticity synergy in additively manufactured NiTi shape memory alloys [PDF]

Nature Communications
NiTi shape memory alloys produced via additive manufacturing are suffering low tensile strength, low total elongation, and unstable superelasticity, thus failing to meet the requirements of practical applications.

Strain glass-induced switch from transformation plasticity to reversible superelasticity in Ti-Zr-Ni-Cu alloys

Materials Research Letters, 2023
Reversibility of phase transformation, a basic requirement for functional properties of shape memory alloys, such as superelasticity, is severely affected by plastic deformation.

Reversible shuffle twinning yields anisotropic tensile superelasticity in ceramic GeSe. [PDF]

Nat Nanotechnol
Superelasticity is a reversible, nonlinear strain response to stress stimuli beyond the linear elastic regime. It is commonly associated with a martensitic transformation in its host material, usually a metal or polymer.

Effect of Fe addition on the microstructure, transformation behaviour and superelasticity of NiTi alloys fabricated by laser powder bed fusion

Virtual and Physical Prototyping, 2023
NiTi-Fe ternary shape memory alloys were produced by laser powder bed fusion (L-PBF) using the pre-alloyed NiTi and elemental Fe powders. A large process window exists to fabricate dense NiTiFe0.3 and NiTiFe0.5 alloys, while severe cracks occur in the ...

The Cyclic Stability of the Superelasticity in Quenched and Aged Ni₄₄Fe₁₉Ga₂₇Co₁₀ Single Crystals [PDF]

Metals, 2023
The effect of aging (at 773 K for 1 h) on the cyclic stability of superelasticity was studied in preliminarily quenched (after annealing at 1448 K for 1 h) Ni44Fe19Ga27Co10 [001]-oriented single crystals.

Active superelasticity in three-dimensional epithelia of controlled shape [PDF]

Nature, 2018
Fundamental biological processes are carried out by curved epithelial sheets that enclose a pressurized lumen. How these sheets develop and withstand three-dimensional deformations has remained unclear.

A Giant Magneto‐Superelasticity of 5% Enabled by Introducing Ordered Dislocations in Ni34Co8Cu8Mn36Ga14 Single Crystal [PDF]

Advanced Science
Elasticity, featured by a recoverable strain, refers to the ability that materials can return to their original shapes after deformation. Typically, the elastic strains of most metals are well‐known 0.2%.
