CCT diagrams examine the progress of transformation as a function of changing temperature. In general, in CCT diagrams, the transformations of austenite are shifted to lower temperatures and longer times. The CCT diagrams allow the prediction of microstructure and hardness, which is not possible using a TTT curve [1].

Iron kinetics; Figure 1. Iron is assiduously conserved and recycled for use in heme and nonheme enzymes. About 1 to 2 mg of iron are lost each day to sloughing of skin and mucosal cells of the gastrointestinal and genitouretal tracts. This obligate iron loss is balanced by iron absorption from the gastrointestinal tract.
