Superelasticity of Geometrically Graded NiTi Shape Memory Alloys

Metals, 2023
A stress plateau with a strain of 5–8% normally occurs during the stress-induced martensite transformation (SIM) of NiTi shape memory alloys. Within the stress plateau, the correlation between the stress and strain is lost, which limits their application

Superelastic graphene aerogel-based metamaterials

Nature Communications, 2022
AbstractUltralight, ultrastrong, and supertough graphene aerogel metamaterials combining with multi-functionalities are promising for future military and domestic applications. However, the unsatisfactory mechanical performances and lack of the multiscale structural regulation still impede the development of graphene aerogels.

Superelastic load cycling of Gum Metal [PDF]

Acta Materialia, 2015
The superelastic beta titanium alloy, Gum Metal, has been found to accumulate plastic strain during tensile load cycling in the superelastic regime. This is evident from the positive drift of the macroscopic stress vs. strain hysteresis curve parallel to the strain axis and the change in its geometry subsequent to every load-unload cycle.

Molecular Dynamics Investigation on Grain Size-Dependent Superelastic Behavior of CuZr Shape Memory Alloys

Metals
The superelasticity of CuZr shape memory alloys (SMAs) originates from stress-induced transformations between the B2 (austenite) and B19’ (martensite) phases. Grain size is a key parameter affecting the superelasticity of shape memory alloys.

Tailoring the superelasticity of NiTi alloy fabricated by directed energy deposition through the variation of residual stress

Materials & Design, 2022
The dynamic thermal cycle of the directed energy deposition process inevitably leads to considerable residual stress within the as-deposited NiTi components.
