Au cu phase diagram. as axes are called phase diagrams. DEF. A phase diagram (or equilibrium diagram) is a diagram with T and composition as axes, showing the equilibrium constitution. The phase diagram of an alloy made of components A and B, for all combinations of T and X B, defines the A-B system. Binary systems have two components, ternary systems three, and so on.

The Al-Si Phase Diagram The binary Al-Si phase diagram was initially studied by Fraenkel of Germany in 1908. It is a relatively simple binary diagram where there is very little solubility at room temperature for Si in Al and for Al in Si. Thus, the terminal solid solutions are nearly pure Al and Si under equilibrium conditions. 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.

Note that, apart from the pure elements, all alloys of Cu and Ni have a range of temperatures over which solidification (freezing) occurs - the field is defined by the liquidus and solidus lines on the phase diagram. We now need to look more closely at the consequences of this.

β phase. Thus, the phase compositions are as follows: Cα = 16 wt% Sn-84 wt% Pb Cβ = 97 wt% Sn-3 wt% Pb (c) The Ag-Cu phase diagram (Figure 9.7) is shown below; the point labeled "C" represents the 55 wt % Ag-45 wt% Cu composition at 900 °C. As may be noted, point C lies within the Liquid phase field.
