A phase diagram of the equilibrium relationship between temperature, pressure, and composition in any system.
the iron iron carbide phase diagram does not have a single microstructure, it has different microstructures depending on the carbon content of the steel.
1) The nonequilibrium martensite does not appear on the diagram; and 2) The diagram provides no indication as to the time-temperature relationships for the formation of pearlite, bainite, and spheroidite, all of which are composed of the equilibrium ferrite and cementite phases.
actually there is no difference in beta phase and alpha phase when we talk about crystal structure of iron. beta phase has the same structure as the alpha phase. the olny difference is the magnetic properties which are absent in beta phase due to the expanded lattice parameter.

If you can solve the beam reactions by the equations of equilibrium, then it is statically deterrminate. If not, that is, more unknown reactions than the equations of equilibrium, then it is indeterminate, and you need to know something about its deformation to solve the reactions.
Phase diagram are also known as thermal equilibrium diagram or a consistutional diagram 1. Different uses of phase diagram are 2. prediction of phase 3. amount of phase 4.composition of phase
meet at the critical point on the diagram.

The simplest phase diagrams are pressure-temperature diagrams of a single simple substance, such as water. The axes correspond to the pressure and temperature. The phase diagram shows, in pressure-temperature space, the lines of equilibrium or phase boundaries between the three phases of solid, liquid, and gas.
At the triple point three phases coexist in equilibrium: solid, liquid and gas.
the triple point
By a line separating the phases
The triple point of a phase diagram is the location where the solid, liquid, and gas phases meet; it is the temperature and pressure at which a given substance can assume any of the 3 usual phases of matter.
