Answer
Two limitations of the iron-iron carbide phase diagram are:
1. The nonequilibrium martensite does not appear on the diagram
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 of ferrite and cementite phases.
