Superelasticity of a Ti$_{50}$Ni$_{25}$CU$_{25}$ shape memory alloy melt spun ribbon

, 2003
The mechanical property of a Ti$_{50}$Ni$_{25}$Cu$_{25}$ melt spun ribbon is studied. After annealed at 500 $^{\circ}$C for 15 minutes, the crystallized ribbon exhibits a transformation hysteresis of 8 $^{\circ}$C and a superelastic shape recovery of up ...

Development of an Inchworm‐Like Dual‐Balloon‐Assisted Colonoscopic Robot Based on a Two‐Segment Extensible Continuum Section

Advanced Intelligent Systems, EarlyView.
This work presents an inchworm‐like dual‐balloon‐assisted colonoscopic robot (IDCR) based on a rod‐driven two‐segment continuum section. The IDCR enables the active straightening of the sigmoid colon through an inchworm‐like locomotion strategy, thereby avoiding loop formation.

Effect of heat treatment on the microstructure and superelasticity of NiTi alloy via selective laser melting

Journal of Materials Research and Technology
In this study, a Ni50.4Ti49.6 shape memory alloy (SMA) was fabricated by selective laser melting (SLM), and it is found that heat treatments were effective to change the phase transformation behavior, microstructure, and superelasticity under compression

Superelastic graphene aerogel-based metamaterials

Nature Communications, 2022
Abstract Ultralight, 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 ...

Superelasticity over a wide temperature range in a NiTiCu shape memory alloy via laser powder bed fusion

Materials & Design
Additively manufactured NiTi-based shape memory alloys (SMAs) can achieve good superelasticity at specific temperatures. However, the realization of superelasticity over a wide temperature range in additively manufactured NiTi-based SMAs has rarely been ...
