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.

Consider the binary phase diagram for copper-nickel system, as shown. The abscissa ranges from 0 wt% Ni (100 wt% Cu) to 100 wt% Ni (0 wt% Cu). Three different phase regions (or fields) appear in the diagram: anα field, a liquid (L) field, and a two-phase α+ L field. The liquid L is a homogeneous liquid solution the phase diagram usually has the general appearance of that in the copper-nickel system shown in Fig. 4.4. Temperature is plotted along the ordinate axis, and the alloy composition is shown on the abscissa axis.

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. By rapidly cooling the Cupronickel or copper-nickel (CuNi) is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese.The copper content typically varies from 60 to 90 percent. (Monel is a nickel-copper alloy that contains a minimum of 52 percent nickel.)Despite its high copper content, cupronickel is silver in colour. Cupronickel is highly resistant to corrosion by salt water ...
