The Effect of Low Temperature Aging and the Evolution of R-Phase in Ni-Rich NiTi

This study investigates the thermal and mechanical properties that arise from aging Ni-rich Ni–Ti (Nitinol) at temperatures below 250 °C, well below those commonly used to fabricate medical devices. We demonstrate that the Ni50.8–Ti49.2 …

SMA Constitutive Modeling Backed Up by 3D-XRD Experiments: Transformation Front in Stretched NiTi Wire

It has been known for a long time that martensitic phase transformation in NiTi shape memory alloys loaded in tension develops inhomogeneously via formation and propagation of macroscopic deformation bands resembling well-known Lüders bands.

Cyclic Properties of Superelasticity in Cu–Al–Mn Single-Crystalline Sheets with Bainite Precipitates

Microstructure, Vickers hardness and cyclic superelastic properties at room temperature were examined for Cu-Al-Mn single-crystalline sheets aged at 200 °C for various time periods. The bainite plates started to appear from about 9 ks and the …

Designing NiTiAg Shape Memory Alloys by Vacuum Arc Remelting: First Practical Insights on Melting and Casting

NiTi-based shape memory alloys are successful owing to its capacity to cover specific applications unreachable by binary NiTi. The additions of ternary, and even quaternary, elements are intended to change specific properties. Known for its …

Stress Wave and Phase Transformation Propagation at the Atomistic Scale in NiTi Shape Memory Alloys Subjected to Shock Loadings

A unique property of Nickel–Titanium (NiTi) shape memory alloys is their ability to dissipate the shock loading energy by two complementary mechanisms: (a) through deformation-induced phase transformations caused by the structural vibrations, and …

Über diese Zeitschrift

The Shape Memory and Superelasticity journal invites original peer-reviewed papers that focus on shape memory materials research with contributions from materials science, materials engineering, experimental and theoretical mechanics, mathematics and physics. Of particular interest is to understand the response of these materials to external stimuli such as force, displacement, temperature, magnetic fields, irradiation, corrosive media and so on in pursuit of uncovering new phenomenon, new materials and new applications as follows: (i) the journal papers will examine these materials utilizing the principles of continuum mechanics, micromechanics, microstructuraly informed constitutive modeling, atomistic models, mathematics of microstructures and other methodologies. (ii) the development and use of advanced experimental techniques to expose and understand the shape memory response including thermal and mechanical cycling, application of magnetic and other external fields, (iii) the exploration and further understanding of shape memory materials due to fatigue, fracture and environmental factors are of significant interest, (iv) novel applications of the materials will be explored in all areas including bio-medical devices, actuators, thin films, robotics, mechanical and aerospace engineering components, civil engineering structures, and micro-electromechanical systems (MEMS).
