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 ...

Niti and NiTi-TiC composites: Part II. compressive mechanical properties

Metallurgical and Materials Transactions A, 1996
The deformation behavior under uniaxial compression of NiTi containing 0, 10, and 20 vol pct TiC participates is investigated both below and above the matrix martensitic transformation temperature: (1) at room temperature, where the martensitic matrix deforms plastically by slip and/or twinning; and (2) at elevated temperature, where plastic ...

Ausforming of NiTi

Journal of Materials Science, 1999
Lattice defects are introduced into stable austenite (β) by hot rolling up to 70% (in one pass) in a temperature range between 900 > TAF > 340 °C (ausforming (AF)). The changes in microstructure, thermal transformation behavior, as well as normal and anomalous properties in stress-, strain-, and temperature-space were studied.

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.

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

Detwinning in NiTi alloys

Metallurgical and Materials Transactions A, 2003
This work focuses on the stress-induced transformation in solutionized and overaged single-crystal NiTi alloys. The potential role of detwinning on the recoverable strains was investigated both theoretically and also with temperature-cycling experiments. The detwinning is the growth of one variant within a martensite in expense of the other.

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.

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.
