Ti–Ni-based alloys are quite attractive functional materials not only as practical shape
memory alloys with high strength and ductility but also as those exhibiting unique physical …

Cu-based shape memory alloys belong to one important class of functional alloys,
presenting shape memory effect and superelasticity due to their reversible martensitic …

In superelastic alloys, large deformation can revert to a memorized shape after removing the
stress. However, the stress increases with increasing temperature, which limits the practical …

Superelasticity associated with the martensitic transformation has found a broad range of
engineering applications,. However, the intrinsic hysteresis and temperature sensitivity of …

A new Japanese nickel-titanium (NiTi) alloy wire was developed by the Furukawa Electric
Co., Ltd. of Japan. This wire was subjected to uniaxial tensile testing and a specially …

Introduction Theshape memoryeffect(SlviE) appears in some special alloys which

This two-part paper reviews the latest developments in the modeling of shape memory
alloys (SMAs) constitutive behavior. The basic properties of SMAs are presented in Part I …

The purpose of this work is to thoroughly understand tension–compression asymmetry in
precipitated NiTi using unique experimental results and micro-mechanical modeling. For the …

Shape memory alloys recover their original shape after deformation, making them useful for
a variety of specialized applications. Superelastic behavior begins at the critical stress …

Both elastic strain energy due to the transformational shape change and frictional resistance
opposing interfacial motion are shown to contribute significantly to the observed …
