continuous cooling transformation

Continuous Cooling Transformation (CCT) describes how a material, like steel, changes its internal structure as it cools gradually from a high temperature. As the temperature drops, the metal's atoms rearrange into different patterns, forming new microstructures such as ferrite, pearlite, or martensite. These changes affect the metal’s strength and hardness. The CCT diagram maps these transformations over different cooling rates, helping to predict the final properties of the material based on how quickly it cools. This process is essential in manufacturing to achieve desired mechanical characteristics in metal products.
