Phase Diagrams • Indicate phases as function of T, Co, and P. • For this course:-binary systems: just 2 components.-independent variables: T and Co (P = 1 atm is almost always used). • Phase Diagram for Cu-Ni system Adapted from Fig. 9.3(a), Callister 7e. (Fig. 9.3(a) is adapted from Phase Diagrams of Binary Nickel Alloys , P. Nash forms with aluminum a series of nickel aluminides; one of them is Al 3 Ni ( in the diagram). Aluminum forms a eutectic with Al 3 Ni at 6.1 wt% nickel. The melting point of the Al-Al 3 Ni eutectic is 640 C and the volume of the Al 3 Ni phase in the eutectic is relatively large (about 9.7 wt%). Furthermore, the Al 3 Ni eutectic phase

The γ-phase is a solid solution with a cubic-F lattice and a random distribution of the different species of atoms. Cubic-F is short for face-centred cubic. By contrast, γ' has a cubic-P (primitive cubic) lattice in which the nickel atoms are at the face-centres and the aluminium or titanium atoms at the cube corners.

system, the phase diagram usually has the general appearance of that shown in Fig. 3. The diagram consists of two single-phase fields separated by a two-phase field. The boundary between the liquid field and the two-phase field in Fig. 3 is called the liquidus; that between the two-phase field and solid field is the solidus.
