Porous NiTi shape memory alloy (SMA) was fabricated by self-propagating high-temperature synthesis (SHS). With this study, a new solution treatment "solution treatment under loading" was applied to porous NiTi SMA fabricated by SHS to determine microstruc

Ti2Ni-based alloys containing oxygen, nitrogen and carbon were investigated regarding their metallographic structures and hydrogenation characteristics. The alloy samples containing these non-metal elements had multi-phase structures composed o

In this study, Ni and Ti with 50.5 at.% Ni powders were blended for 12 h and cold pressed in the different pressures (50, 75 and 100 MPa). Then, the porous NiTi alloy compacts obtained were synthesized by SHS (self-propagating high-temperature synthesis)
Synthesis of NiTi intermetallics by self-propagating combustion
Yeh,Sung
, p. 79 - 88 (2004)
The production of NiTi intermetallic compounds from elemental powder compacts was conducted by self-propagating high-temperature synthesis (SHS) in this study. Effects of initial sample density, preheating temperature, and Ni particle size on the combustion characteristics, as well as on the final composition and morphology of products were studied. For the samples with densities between 50 and 60% theoretical maximum density (TMD) under preheating temperatures in the range of 100-300°C, the synthesis process showed two consecutive combustion stages, including the propagation of combustion front and the subsequent bulk combustion. Under these conditions, high-density products containing NiTi as the major phase with small amounts of secondary phases of NiTi2 and Ni3Ti were obtained. However, porous combustion products with a significant amount of unreacted Ni were produced from the 45% TMD samples under preheating temperatures of 100 and 150°C, due to the lack of the second combustion stage. The amount of unreacted Ni in the final composition was greatly reduced by increasing the initial sample density and preheating temperature, or by using smaller Ni particles in the samples. In addition, the use of smaller Ni particles also led to an increase in the product density up to about 95% relative to the density of NiTi intermetallic.
PHASE RELATIONS AND DIFFUSION PATHS IN THE Ti-Ni-Fe SYSTEM AT 900 degree C.

A study was made of the 900 degree C cross section through the ternary phase diagram Ti-Ni-Fe by means of the diffusion couple technique and by investigating equilibrated alloys. The course of a number of diffusion paths was established. Use was made of optical, microprobe, and X-ray analyses. Some hitherto unaccountable results mentioned in the literature have been explained.
