This zone is represented at the left of the diagram where the alloy is in solid solution (phase ), a face centred cubic structure like copper. For the typical alloy CuBe1.9 (1.8 to 2% of beryllium) the alloy is in the phase between 720°C and 860°C. For industrial purposes the solution heat treatment is done between 750° and 800°C.

The maximum of this peak corresponds to a temperature of ~380 °C that is very close to the order-disorder temperature boundary for the Cu-56Au alloy on the copper-gold phase diagram. It is surprising but the temperature derivative of the electrical resistivity obtained at cooling has only one maximum (blue curve in Fig. 6 b).

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.
