Alloys are metallic compounds made up of one or more metals and non-metals. They are usually made by melting the substances, mixing them together, and then letting them cool to room temperature. 

Examples of alloys include:
Steel: A combination of iron (metal) and carbon (non-metal)
Bronze: A combination of copper (metal) and tin (metal)
Brass: An alloy formed by mixing two metals, copper and zinc 

A phase diagram, also known as a constitutional diagram, is a graphical representation of the composition and temperature limits of phase fields in an alloy system. It shows the equilibrium constitution of an alloy made of components A and B for all combinations of T and XB. 

The phases present in an alloy depend on the alloy composition and the thermal treatment to which the alloy has been exposed. The composition of an alloy is given in the form A - x%B.
