Abstract: | The present study of the binary Ti–Rh system provides a revised phase diagram clarifying controversial results in the literature. Various experimental methods were applied: electron probe microanalysis, X-ray diffraction, and differential scanning calorimetry. The tie-lines of two-phase equilibria and the second-order transition A2/B2 were identified by means of diffusion couple experiments and by analysis of annealed bulk alloys. The diffusion couple experiments revealed two phenomena which were identified as pseudo-interfaces: one associated with crossing the stoichiometric composition of the B2 phase; a second between pure Rh and the Rh-rich solution. |
