The Steel Model Library makes it easy to set up time-temperature-transition calculations using a TTT template that is accessed directly from the homescreen of Thermo-Calc. The template has several preconfigured settings to help you set up and calculate the TTT diagram using the Martensite Temperatures and Pearlite Property Models.
The template also includes a plotting mode called TTT mode, which is used to define the Temperature on the y-axis and Time on the x-axis for all selected quantities. For example, as shown in the image here, Pearlite will show transformation times for 2%, 50%, and 98% Pearlite, and time independent results, like the Ms temperature, will be drawn as a horizontal line.
The plot is a time-temperature-transformation (TTT) diagram in a basic Fe-10Cr-1C alloy (mass %) made using the TTT-template and the TTT plotting mode which shows transformation times for 2%, 50%, and 98% Pearlite and time independent results, like the Ms temperature, which are drawn as a horizontal line.
