Effect of mechanical cycling on the pseudoelasticity characteristics of TiNi and TiNiCu alloys

Materials Science and Engineering: A, 1995
This paper presents the findings of an experimental study of how mechanical cycling of TiNi and TiNiCu shape memory alloys in the pseudoelastic (PE) state affects their residual elongation after unloading, their critical stress for martensite formation and their hysteresis or amount of energy dissipated during one cycle. Specimens were cycled in two

Kinetics of the crystallization of amorphous TiNi and TiNiSi alloys

Materials Science and Engineering: A, 1994
Abstract Three binary TiNi alloys and three ternary TiNiSi alloys were rapidly quenched by the splat-cooling method and found to be completely amorphous. Their crystallization behaviour was studied by dynamic differential scanning calorimetry and by isothermal heat treatment followed by X-ray diffraction and transmission electron microscopy.

Characterization and reliability of Ti/Ni/Au, Ti/Ni/Ag and Ti/Ni back‐side metallizations in the die‐bonding of power electronic devices

Surface and Interface Analysis, 1994
Abstract The surface compositions of three different back‐side metals: Ti/Ni/Au 0.1/0.4/0.1 μm, Ti/Ni/Ag 0.1/0.4/0.1 and 0.1/0.4/2 μm and Ti/Ni 0.1/04 μm after thermal treatment at 180°C in air were investigated by means of XPS technique.

Structure of a Ti-Ni alloy produced by annealing of a multilayer Ti/Ni microcomposite

Russian Metallurgy (Metally), 2011
A multilayer microcomposite that consists of alternating nickel and titanium microlayers and corresponds to a near-equiatomic Ti-Ni alloy composition in the volume proportion is studied. The Ti/Ni composite is produced by vacuum rolling of a multilayer stack and subjected to heat treatment in the temperature range from 500 to 1000°C.

Temperature dependence of the mixing enthalpy of liquid Ti–Ni and Fe–Ti–Ni alloys

Journal of Non-Crystalline Solids, 1999
Abstract Using electromagnetic levitation alloying calorimetry, the concentration and temperature dependence of the mixing enthalpy of liquid Ti–Ni and Fe–Ti–Ni alloys has been determined. For the Ti–Ni alloys, the measurements have been carried out at 1800 and 1980 K.

Materials Science and Engineering: A, 1999
Abstract Rapidly solidified ribbons of Ti–Ni–Zr and Ti–Ni–Hf shape memory alloys for high-temperature applications have been produced using a planar flow casting technique. Calorimetric and mechanical measurements, as well as transmission electron microscopy (TEM) observations have been performed.

A reassessment of the TiNi system

Calphad, 1993
Abstract The Ti-Ni system has been reevaluated. A subregular solution model is used for the liquid and regular ones for the terminal solid solutions ((α Ti), (β Ti),(Ni)). The compounds, Ti 2 Ni and TiNi 3 , are treated as line compounds, while TiNi is described by a three-sublattice model.

Cyclic stress-strain characteristics of TiNi and TiNiCu shape memory alloys

Materials Science and Engineering: A, 1995
The authors have examined the responses of three types of TiNi and three types of TiNiCu shape memory alloys in a pseudoelastic state to mechanical cycling in hard cycles with a constant emax and in soft cycles with a constant σmax. It was found that the transformation stress of the B2 parent phase into martensite and the hysteresis (or the amount ...
