| Description | The Ti-Mn-N system plays a significant role for technically important alloys. This system has not been experimentally and theoretically studied in the past. This work presents a thermodynamic modelling of this ternary system based on thermodynamic assessments of the constitutive binary systems Mn-N and Ti-N and a new re-assessment of the Ti-Mn system, supported by hitherto unpublished experimental data. Because the binary Ti-Mn system is the crucial system for many applications like hydrogen storage materials, titanium aluminum duplex alloys with high strength intermetallics for aerospace and turbine applications etc., careful thermodynamic re-optimization respecting new ab-initio data for the Laves phase TiMn2 (C14) and new experimental data has been performed first to ensure correct phase relations from this binary sub-system. The problem of the modelling of phase equilibria in the ternary Ti-Mn-N system is discussed in view of the new thermodynamic description of the Ti-Mn system. |
