Heat Treatment of Steels

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.
