time-temperature-transformation

Time-Temperature-Transformation (TTT) diagrams are tools used in materials science to show how different cooling rates affect the structure of metals. When metal cools from a high temperature, its internal structure can change depending on how quickly it cools. Slow cooling may produce soft, ductile structures, while rapid cooling can create hard, brittle ones. The TTT diagram maps out the relationships between temperature, time, and the resulting microstructure, helping engineers control the properties of metals like steel by selecting appropriate cooling procedures for desired characteristics.
