Using the isothermal transformation diagram for an iron-carbon alloy of eutectoid composition. The nature of the final microstructure of the specimen which is subjected to various heat treatment processes can be found out by use of figure 1022 complete isothermal transformation diagram for an iron carbon alloy of eutectoid composition. However, one of the limitations of the diagrams is that the transformations are based on isothermal processes. Heat-treating operations are not carried out using isothermal process, but using continuous cooling. As a result, the TTT curves representing the transformation of austenite are not strictly applicable to heat-treating operations.
