CuAl2, FeAl3 and MnAl3 are constituents in aluminium alloys. The association of phases in distinct fashions may be refers to as a structural constituents of alloy. Structural Constituents:- The phases in alloys are not uniformly distributed throughout the structure.

Equilibrium:- Minimum free energy of a system under specified combination of pressure, Temperature, Composition and total volume is called Equilibrium state.Дegree of freedom:- It is the number of external and internal variables of the system that may be changed independently without causing appearance or disappearance of a phase. there can be Ternary or Quaternary system too. A system having two component called as Binary system. A system having one component called as Unary system. composed of gases, liquids, solids or their mixtures.Д¬omponents:- It may be elements, compounds or solutions. System:- Substance or group of substance isolated from its surrounding in such a way that it completely unaffected by surrounding. Ternary (three Component) phase diagram and so onвЂ¦.ДЄny structure which is physically distinct microscopically may be considered as a phase.(uniform chemical compositions). Binary (two Component) phase diagram here pressure is constant and temperature on the vertical axis and compositions on the horizontal axis. Sometimes it is used to some extent in predicting the phase relations, compositional changes and structure in the system not at equilibrium.Д¦ Classification Unary (one Component) phase diagram plotted as pressure on the vertical axis and temperature on the horizontal axis. This limits the use of equilibrium diagram. In actual practice as under welding and casting conditions equilibrium conditions are not obtained. structural changes due to heat treatment, casting etcвЂ¦вЂ¦вЂ¦ Marks Liquidus and Solidus lines.ДҐ Limitations Equilibrium condition means a very slow process taking infinitely long time for any changes to occurs. Study of phase separation, solidification of metal and alloys, purification of material. Shows the relationship between the composition, temperature and structure of an alloy in series. Shows the phases which exists in equilibrium in any combination of temperature and compositions. Due to this phase diagram are called Thermal Equilibrium Diagram. So phase diagram changes due to variation in temperature & composition. At atmospheric value pressure assume to be constant. very slow heating or cooling process.ДЇor equilibrium three controllable variable are:- Temperature, Pressure and Composition. Equilibrium condition means a very slow process taking infinitely long time for any changes to occurs. Definition:- The Diagram which records the type of phase in material and change in phase is called Equilibrium Diagram.
