14 So What’s a CCT Diagram? Phase Transformations and Production of Microconstituents takes TIME. Higher Temperature = Less Time. If you don’t hold at one temperature and allow time to change, you are “Continuously Cooling”. Therefore, a CCT diagram’s transition lines will be different than a TTT diagram.

Phase diagram Wikipedia

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.
