Nickel aluminum phase diagram. Phase equilibria in the Ni-Al-Cr system at 1150°C were investigated by using annealed ternary alloys and diffusion couples. The phase constitutions, microstructures, and tie-lines were determined by conventional techniques, including X-ray diffraction, scanning electron microscopy and electron probe microanalysis. The solubility limits of Cr was found to be about 9at.% in the γ' and 17at ... Superalloys can be based on iron, cobalt or nickel, the latter being best suited for aeroengine applications. The essential solutes in nickel based superalloys are aluminum and/or titanium, with a total concentration which is typically less than 10 atomic percent. This generates a two-phase equilibrium microstructure, consisting of gamma ( γ ... aration techniques for aluminum metallographic samples. Phase diagrams and identification of constituents, important to the interpretation of struc tures, are covered in Ref 2 and 3. Many of the changes that become apparent with the examination of aluminum macrostructure and microstructure occur simultaneously with Aluminium increases strength, seawater and scaling resistance. Beryllium has the strongest effect on mechanical properties after age-hardening. The solubility of carbon in nickel (max. 0.18%) is severely reduced as copper content increases - it is about 0.01% with a copper content of 90%. Carbon is not detrimental in Cu-Ni alloys.
The aluminium bronze and nickel aluminium bronze equilibrium phase diagram s shown in Figures 34 and 35 can appear rather complicated with a number of microstructural phase s possible. In the binary system of copper and aluminium, Figure 34, for up to approximately 9% aluminium, the equilibrium metal structure is a single (alpha) phase.

A preliminary study of the region of stability of the Ni 5 Al 3 phase in the nickel-aluminum binary phase diagram has been made using powder x-ray diffraction and optical and electron microscopy. Ni 5 Al 3 is stable below about 700°C. The variation of the lattice parameters and morphology of the Ni 5 Al 3 precipitates formed in 63 and 70 at.% nickel-aluminum alloys as functions of the ... 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.

We will limit our discussion of phase diagrams of multi-component systems to binary alloys and will assume pressure to be constant at one atmosphere. Phase diagrams for materials with more than two components are complex and difficult to represent. An example of a phase diagram for a ternary alloy is shown for a fixed T and P below.
