Ni ti phase diagram

The Ni-Ti equilibrium phase diagram, TTT diagram, and knowledge about kinetic processes (e.g., diffusion, precipitation, phase transformations) are all invoked for the analysis. Students enjoy the ability to plan parts of the experiment and witnessing the connection

The portion of the Cu-Ti equilibrium diagram in Fig. 1b indicates a polymorphic transformation of the Cu 4 Ti phase; it suggests that the tetragonal D1 a phase is the stable phase below ≈ 500°C and that the orthorhombic Au 4 Zr-type structure is the equilibrium high temperature phase.

Research on phase diagrams and phase equilibria of Nb-Ni-Ti system was originated from the development of Ni-based superalloys. The pseudo-binary phase diagram of TiNi 3 -NbNi 3 was obtained in 1958, and the isothermal sections of phase diagram of Ni-rich corner in Nb-Ni-Ti system at 900 and 1000 °C were acquired in 1966 [].The development of wide hysteresis shape memory alloys ...

Ni ti phase diagram.

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 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.

At low temperature, Ni-Ti alloy exhibits a monoclinic distorted crystal structure, that is, a martensitic phase. At this stage, the alloy can be easily deformed. The temperature at which the austenitic phase transforms into a martensitic one is called the transformation temperature.

The phase equilibria in the Nb-Ni-Ti-Zr quaternary system have been studied using the CALPHAD method. Among the four ternary systems present in the quaternary phase diagram, the Nb-Ti-Zr ternary system was described using a simple ternary extrapolation of the constituent binary systems with no additional ternary parameters.
