In the **'Phase summary'** and **'Phase details'** window, only the FCC_A1 phase is denoted as active (mole fracton = 1). We can now proceed with this initial condition. For convenience, store this (current) state in a calculation state with the name **'Start austenite'** by selecting **'Global' -> 'CalcStates' -> 'Create...'**. | In the **'Phase summary'** and **'Phase details'** window, only the FCC_A1 phase is denoted as active (mole fracton = 1).

In the same way, similar to the evaluation of the dependence of the T<sub>0</sub>- temperature on the chromium content, it is possible to calculate the T<sub>0</sub>- temperature as a function of the carbon content. Therefore, rename the **'_default_'** buffer selecting **'Global' -> 'Buffers' -> 'Rename...'** and give it the name **'T0-chromium'**. Then create a new buffer (**'Global' -> 'Buffers' -> 'Create...'**) with the name **'T0-carbon'** and load the calculation state **'Start austenite'** (make sure that the current buffer is the **'T0-carbon'**). Analogously to the calculation before, carry out a stepped calculation. Press **'Calc' -> 'Stepped calculation ...'** or press **Ctrl+T**, enter the following settings and press **'Go'**. | In the same way, similar to the evaluation of the dependence of the T<sub>0</sub>- temperature on the chromium content, it is possible to calculate the T<sub>0</sub>- temperature as a function of the carbon content.

There is no need to create a new plot in order to display the graph for the T<sub>0</sub>-temperature dependence for varying carbon content. The T<sub>0</sub>- temperature line in the figure can be simply changed by **switching** from **'T0-chromium'** buffer to the **'T0-carbon'** buffer **in the options window**. | There is no need to create a new plot in order to display the graph for the T<sub>0</sub>-temperature dependence for varying carbon content.

Press **'OK'** twice and insert the experimental data into the plot as a new series (right-click in **'options'** window and select **'New series' -> 'table experimental data'**) and switch to **'Exp. data'** in **'connected to'** box (see also [[tutorials:T5 | Tutorial 5]]). | Press **'OK'** twice and insert the experimental data into the plot as a new series (right-click in **'options'** window and select **'New series' -> 'table experimental data'**) and switch to **'Exp. data'** in **'connected to'** box (see also [[tutorials:T5 | Tutorial 5]]). |
