INNOVATIVE USE OF SHAPE MEMORY ALLOYS AS REINFORCEMENTS FOR CONCRETE BEAM-COLUMN JOINTS: AN OVERVIEW
Mağallaẗ Al-kūfaẗ Al-handasiyyaẗ, 2023 Shape memory alloys have two unique properties of shape memory effect (SME) and superelasticity (SE) that are the ability for large inelastic deformations recovery after heating (SME) and stress removal (SE).

Research Progress of Fe-Based Superelastic Alloys
Crystals, 2022 In recent years, superelastic alloys have become a current research hotspot due to the large recoverable deformation, which far exceeds the elastic recovery. This will create more possibilities in practical applications.

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 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.

Biomimetic superelastic graphene-based cellular monoliths [PDF]
Nature Communications, 2012 Many applications proposed for graphene require multiple sheets be assembled into a monolithic structure. The ability to maintain structural integrity upon large deformation is essential to ensure a macroscopic material which functions reliably. However, it has remained a great challenge to achieve high elasticity in three-dimensional graphene networks.
