TTT Diagram or Time-Temperature-Transformation Diagram to mainly explain you about isothermal transformation.
What is TTT Diagram? TTT stands for Time Temperature Transformation. It is diagram which explains about temperature of time for a steel alloy. It is used to know when is the beginning and the ending for an isothermal transformation from an alloy. TTT diagram shows when a specific transformation begins and ends. It also shows what percentage of transformation at a specific temperature is reached. And here are some example of its diagrams.
