WebMar 23, 2024 · TTT diagrams TTT diagram stands for “time-temperature-transformation” diagram. It is also called isothermal transformation diagram Definition: TTT diagrams give the kinetics of isothermal transformations. Determination of TTT diagram for eutectoid steel Davenport and Bain were the first to develop the TTT diagram of eutectoid steel. Isothermal transformation diagrams (also known as time-temperature-transformation (TTT) diagrams) are plots of temperature versus time (usually on a logarithmic scale). They are generated from percentage transformation-vs time measurements, and are useful for understanding the transformations of an alloy steel at elevated temperatures.
