Phase Equilibrium & Phase Transformation

Phase Equilibrium:

          The state of a system where the phase charecteristics remain constant over indefinite time periods. At equilibrium the free energy is a minimum.
        In an equilibrium diagram, liquid is one phase and solid solution is another phase.

Phase Transformation:

          A change in the number and/or character of the phases that constitute the microstructure of an alloy.
