NiTi memristive behavior

Microelectronic Engineering, 2019
Abstract In this paper, the experimental study and confirmation of the memristive behavior demonstrated by nanowires made of a smart alloy, namely NiTi, are presented. Further contribution to the characterization of the proposed novel NiTi memristor, included measurements in the ac domain, confirming the memristive nature of these NiTi wires/devices.

Fatigue crack-growth in shape-memory NiTi and NiTi–TiC composites

Materials Science and Engineering: A, 2000
Abstract An experimental study was conducted to examine the room-temperature fatigue crack-growth characteristics of shape-memory NiTi matrix composites reinforced with 10 and 20 vol.% of TiC particles. Microstructural characterization of these hot-isostatically-pressed materials shows that the TiC particles do not react with the NiTi matrix and that

Fabrication Of Hard Coatings On NiTi Instruments

Journal of Endodontics, 2003
The present study was designed to compare the nature of modified surface layers obtained by two different procedures on endodontic files made of NiTi alloy: the procedures were arc evaporation physical vapor deposition and thermal metal organic chemical vapor deposition (MOCVD). Experimental samples were GT Rotary Instruments.

Transformation behavior in NiTi-20Ta and NiTi-20Nb SMAs

2019
Shape memory alloys Ni30Ti50X20 (at.% X = Nb, niobium, and Ta, tantalum) were produced through arc-melting method. Phase transformation temperatures were studied by using differential scanning calorimetry (DSC), and microstructures were examined with the aid of optical microscopy, scanning electron microscopy-energy dispersive X-ray (SEM-EDX) and X-ray

Niti and NiTi-TiC composites: Part III. shape-memory recovery

Metallurgical and Materials Transactions A, 1996
The transformation behavior of near-equiatomic NiTi containing 0, 10, and 20 vol pct TiC particulates is investigated by dilatometry. Undeformed composites exhibit a macroscopic transformation strain larger than predicted when assuming that the elastic transformation mismatch between the matrix and the particulates is unrelaxed, indicating that the ...

Selective de-alloying of NiTi by oxochloridation

Corrosion Science, 2008
Abstract The systematic modification of a nickel–titanium-alloy by annealing in a complex gas atmosphere was investigated. A mixture of HCl and H2O in inert argon was chosen. The reaction kinetics was investigated at 600 °C, 700 °C and 800 °C. The reaction kinetics displayed a significant dependence on the temperature.

Microstructure and Strength of NiTi-Nb Eutectic Braze Joining NiTi Wires

Metallurgical and Materials Transactions A, 2015
NiTi wires were brazed together via liquid eutectic formation between NiTi and Nb powders deposited at the wire contact region. The brazed region shows proeutectic NiTi(Nb) in contact with the wires, sandwiching a NiTi-Nb eutectic structure, whose microhardness and stiffness, as characterized via nanoindentation, are higher than the NiTi wires, while ...
