The phase diagram of an alloy made of components A and B, for all coinations of T and X B, defines the A-B system. Binary systems have two components, ternary systems three, and so on. Commercial alloys may contain 10 or more elements, but in all cases there is one principal element (copper alloys, aluminium alloys and so on) to which other
