System the phase diagram usually has the general appearance of that shown in fig.

Zinc copper phase diagram. A region of the copper zinc phase diagram that has been enlarged to show eutectoid and peritectic invariant points c 74 wt zn and p 598 c 786 wt zn respectively. For example in a copperzinc brass the components are cu and zn. From the copper zinc phase diagram we can see the solid solubility of zinc in copper for concentrations of zinc upto about 30 at at equilibrium the alloy should be of a single phase.

Figure by mit ocw. The diagram consists of two single phase fields separated by a two phase field. Before interpret and utilize phase diagram it is necessary to understand component system and phase.

Like two simple eutectic diagrams joined back to back intermetallic compound with distinct chemical formula not a solid solution. For example cartridge brass is 70 wt copper 30 wt zinc 15 16 the magnesium lead phase diagram. The boundary between the liquid field and the two phase field in fig.

Brasses are copper alloys with zinc see the cu zn phase diagram. That between the two phase field and solid field is the solidus. Note that each single phase field is separated from other single phase fields by a two phase field.

3 is called the liquidus. Components are pure metals andor compounds of which an alloy is composed. Alpha brasses are often seen with a single phase however this usually arises due to annealing.

Commercial brasses are copper rich copper zinc alloys.
