It is not all that different from the unofficial TTT diagram for the pure iron … 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. northman\\u0027s sporting goods https://payway123.com
