Pseudoelastic Behavior of Fe–Al Polycrystals
Pseudoelastic behavior of Fe–Al polycrystals at room temperature was examined focusing on Al concentration, the crystallographic texture and the grain size. Perfect pseudoelasticity derived from the reversible motion of 1/4 ‹111› superpartial dislocations dragging the anti-phase boundaries (APB) took place in Fe–25.0at%Al polycrystals at a total strain

Optimization of a Pseudoelastic Absorber for Vibration Mitigation
Abstract Dynamic vibration absorbers (DVAs) have received special attention in recent years due to their capability to reduce structural vibrations of a primary structure. In this work, a DVA of the Tuned Mass Damper type based on a Shape Memory Alloy (SMA) element with pseudoelastic behavior is considered.

CHARACTERISTICS OF DEFORMATION AND TRANSFORMATION PSEUDOELASTICITY IN Ti-Ni ALLOYS
Although the Ti-Ni alloy is the most important material for applications, there has been no systematic work on its deformation behavior. In the present report, the effects of ageing, Ni-content and annealing right after cold work on the shape memory ...

Stabilization of L‐PBF Ni50.7Ti49.3 under low‐cycle loading was investigated. Recoverable strain after cycling was dependent on the amount of applied load. Recovery ratio was 53.4% and 35.1% at intermediate and high load, respectively. The maximum total strain reached 10.3% at a high load of 1200 MPa.

Pseudoelasticity of D03-Type Fe3Al and Fe3Ga-Based Alloys
The pseudoelastic behavior of Fe3Al and Fe3Ga alloys with the D03 structure is reviewed. In general, pseudoelasticity of shape memory alloys is based on a thermoelastic martensitic transformation.

Self‐Expanding Cardiovascular Stents: Potentials and Challenges of Shape Memory Biomaterials
ABSTRACT Cardiovascular diseases affect a large portion of the global population and remain leading causes of morbidity and mortality. Endovascular stenting, a minimally invasive procedure, enables the insertion and deployment of stents to restore arterial patency without open surgery.
