Phase transformations in nickel-rich nickel-titanium alloys : influence of strain-rate, temperature, thermomechanical treatment and nickel composition on the shape memory and superelastic characteristics

The Ni-Al-Ti ternary phase diagrams show the γ and γ' phase field. For a given chemical composition, the fraction of γ' decreases as the temperature is increased. This phenomenon is used in order to dissolve the γ' at a sufficiently high temperature (a solution treatment) followed by ageing at a lower temperature in order to generate a uniform and fine dispersion of strengthening precipitates.

Nickel titanium, also known as Nitinol, is a metal alloy of nickel and titanium, where the two elements are present in roughly equal atomic percentages.Different alloys are named according to the weight percentage of nickel; e.g., Nitinol 55 and Nitinol 60.It exhibits the shape memory effect and superelasticity at different temperatures.. Nitinol alloys exhibit two closely related and unique ... The ternary phase diagrams relevant to the nickel-rich region of the nickel­ aluminum-chromium-titanium system are shown in figures 1 to 3 and were taken from references 7, 8, and 9. Note that fortunately the investigators did determine tie lines in these systems.

STRUCTURE OF NICKEL-TITANIUM The crystal structure of NiTi alloy at high temperature ranges (100°C) is a stable, body-centred cubic lattice which is referred to as the austenite phase or parent phase. When it is cooled through a critical transformation temperature range (TTR), the alloy shows dramatic changes in its modulus of elasticity ... The Ni-Al-Ti ternary phase diagrams for the nickel - aluminium - titanium system show this two phase fields created. For a given chemical composition, the fraction of one phase decreases as the temperature is increased. Ni. Nickel solubility in titanium is ∼ 10 at.% at the subsolidus temperature. Production of the Ti-Ni-Ru Phase Diagram Starting materials for the synthesis of the Ti-Ni-Ru alloys were: ruthenium powder (99.95 mass%), nickel (99.99 mass%) and iodised titanium (99.98 mass%).
