Shape memory effect of antiferroelectrics
Ferroelectrics, 2001Abstract Pb(Zr0.95 Ti0.05)O3 (PZT) antiferroelectric ceramics have been fabricated by sintering and their structure and phase transition behavior were studied by X-ray diffraction (XRD) and Differential Scanning Calorimetry (DSC). The phase transition order is anti-ferroelectric (ARE) → ferroelectric (FE) → Paraelectric with structure changes ...

Understanding shape memory requires a thermodynamic approach that takes into account the structure of the solid and the mechanical properties resulting from it. For this reason, the crystallographic and thermodynamic aspects of shape memory effects will be discussed below to the extent to which they are relevant to the development of microactuators ...

Abstract We are now in a position to discuss the shape-memory effect. Recall from the introduction that this is the ability of certain materials to recover, on heating, apparently plastic deformation sustained below a critical temperature.

Theory of pseudoelasticity and the shape-memory effect
Physical Review B, 1992A theory of pseudoelasticity has been developed in the phenomenological Ginzburg-Landau scheme. The system characterized by «stripe»-type ferroelastic domain structure has been discussed using the transfer-integral method, which directly gives the equilibrium density of domain boundaries and the response of domain pattern against the external stress ...

Various shape memory effects of stimuli-responsive shape memory polymers
Smart Materials and Structures, 2013One-step dual-shape memory polymers (SMPs) recover their original (permanent) shape upon small variation of environmental conditions such as temperature, electric field, light, magnetic field, and solvent/chemicals. For advanced applications such as aerospace and medical devices, complicated, multiple-step, spatially controllable, and two-way shape ...

TIG Welding and Shape Memory Effect of TiNi Shape Memory Alloy
Journal of Intelligent Material Systems and Structures, 1996In the present study, with respect to TIG welding for a TiNi shape-memory alloy wire and sheet, the optimum welding schedule was decided based on the breaking load of the weld and its standard deviation. By performing the cyclic loading-unloading and heating-cooling tests in the neighborhood of the weld, the shape memory effect was investigated.

Phase transition of shape-memory effect in glassy shape-memory polymers
SPIE Proceedings, 2013Shape-memory materials (SMMs) are fascinating materials, with the potential for application as “smart materials” and also as actively moving materials, which can change their shape in a predefined way between/among shapes in presence of an appropriate stimulus.
