Abstract
The experimental information on the solubility in the various Fe phases of TiC, TiN and solutions between them has been assessed using thermodynamic modelling. A set of values for the model parameters is proposed and it is capable of reproducing the experimental information with reasonable accuracy. It is noted that the TiC-TiN solution was found to have a small negative deviation from ideality. A previous assessment resulted in a strong, negative deviation from ideality but it did not reproduce all the information on the solubility very well.
