Applications of Shape Memory Alloys for Neurology and Neuromuscular Rehabilitation

Journal of Functional Biomaterials, 2015
Shape memory alloys (SMAs) are a very promising class of metallic materials that display interesting nonlinear properties, such as pseudoelasticity (PE), shape memory effect (SME) and damping capacity, due to high mechanical hysteresis and internal ...

Influence of Fe on shape memory effect of Ni-Mn-Ga alloy microwire

Cailiao gongcheng
The shape memory effect of alloy microwire with Fe replacing Ga based on Ni-Mn-Ga alloy microwire was analyzed. Ni-Mn-Ga-Fe alloy was prepared by vacuum tungsten arc melting furnace and the parent alloy was prepared by a high vacuum precision melt ...

Two-way Shape Memory Effect of NiTi under Compressive Loading Cycles

Physics Procedia, 2011
AbstractIn this study, the two-way shape memory effect (TWSME) of a Ni-54.5 at.% Ti alloy was investigated experimentally to develop a NiTi linear actuator. The two-way shape memory effect was induced through a compressive shape memory cycle composed of four steps: (1) loading to maximum deformation; (2) unloading; (3) heating; (4) and cooling.

Flight experience and executive functions predict unlike professional pilots who are limited by the FAA's age rule, no age limit is defined in general aviation (GA) [PDF]

, 2010
Unlike professional pilots who are limited by the FAA's age rule, no age limit is defined in general aviation (GA). Some studies revealed significant aging issues on accident rates but these results are criticized.

Recycling probability and dynamical properties of germinal center reactions

, 2001
We introduce a new model for the dynamics of centroblasts and centrocytes in a germinal center. The model reduces the germinal center reaction to the elements considered as essential and embeds proliferation of centroblasts, point mutations of the ...

A study of two-way shape memory effect in CuZnAL aLloy

Journal de Physique III, 1991
A new comparatively convenient training program for two-way shape memory effect (TWSME) in CuZnAl alloy was introduced. The internal friction, frequency, zero point shift of torsion pendulum and electric resistance were synchronistically measured during TWSME cycle.
