A phase can be defined as a physically distinct and chemically
homogeneous portion of a system that has a particular
chemical composition and structure.
Water in liquid or vapor state is single phase. Ice floating on
water is an example two phase sy
Eutectic Phase diagram
In the eutectic system between two metals A and B, two
solid solutions, one rich in A () and another rich in B () form.
In addition to liquidus and solidus lines there are two more
lines on A and B rich ends which define the solubil
