| Create a precipitate phase **CEMENTITE_P0**, using **'Global > Phase status'**. In the **'Nucleation"** tab -> **'Controls'** subtab, change the **'Nucleus composition'** model from **'ortho-equilibrium'** to **'para-equilibrium'** using the drop-down menu. **'Para-equilibrium'** means that the nucleus is assumed to have the same composition in terms of substitutional elements as the matrix from which it forms, and only the carbon is partitioned between the two phases. In the **'ortho-equilibrium'** model, by contrast, the composition of the nucleus is calculated assuming full equilibrium with the BCC_A2 matrix. In the **'Nucleation > Sites'** tab, set the nucleation sites to **'Dislocations'** (remove the tick from 'bulk') | Create a precipitate phase **CEMENTITE_P0**, using **'Global > Phase status'**.
