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.

Hysteresis in NiTi alloys

Journal de Physique IV (Proceedings), 2004
Large changes in hysteresis are reported as a function of applied stress under thermal cycling experiments in NiTi single crystals. In the low Ni alloy the thermal hysteresis expanded with increasing stress while in the high Ni alloy the thermal hysteresis contracted with increasing stress.

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.

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.

The Manufacture of NiTi Foams

Adaptive Structures and Materials Systems, 2002
Ongoing research is presented on processing of NiTi-based shape memory alloy (SMA) foams. The aim is to demonstrate a new class of materials that combine the advantages of light-weight metallic foams with the strain recovery and energy-dissipation capability of SMAs.
