44 ni ti phase diagram

Phase diagrams of the Ti-Ru and Ti-Ni binary boundary systems up to 50 at.% Ni are well known (9), the main features are: Ti-Ru System The equiatomic phase (8) in the Ti-Ru system has a CsC1-type cubic crystal structure and ciys- tallises from the melt at 2160 f 50°C. The Al-Ni-Ti phase diagram has been thermodynamically assessed and a consistent set of thermodynamic functions has been developed. The thermodynamic modeling is based on an experimental investigation of the phase equilibria in the composition range of 0.1⩽x Al ⩽0.7. Alloys were prepared by argon-arc or vacuum-electron beam melting of elemental powder blends.

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.

Ni ti phase diagram. Ti-Cu-Ni phase diagram was assessed and two isopleths were estimated to interpret the microstructure morphology and phases formed. The formation of brazing microstructure can be well described from the principles of phase diagram, solidification path and phase transformation.

The thermodynamic description of the Ti-Ni-Al phase diagram was recently optimized by Dupin [1]. Due to the lack of experimental data on the Ti-Al side of the phase diagram, however, the work focused on the Ni-rich region with more than 50 at% Ni. In order to cover the white spot of the system, experiments were J. Kapala, D. Kath, and K.

The calculations for Ni-Al can then be combined with those of Ni-Ti and Al-Ti as part of the calculation for the Ni-Al-Ti ternary system. A calculated isothermal section at 1000°C is shown in Fig.2 below. The diagram is in excellent agreement with that observed in practice. As is known in superalloys, Ti partitions
