| Description | Mechanical and physical properties have been determined for polycristalline TiMn2. Based on experimental data on 30 alloys prepared by various methods phase relations in the ternary system Ti-Mn-N have been established and calculated for the isothermal section at 900 °C. The thermodynamic modelling relies on existing thermodynamic assessments of the Mn-N and Ti-N binary systems and on our recent modelling of the Ti-Mn system, which is characterized by a significantly higher thermodynamic stability of the C14-type Laves phase than hitherto assumed in the literature. The higher stability ensures consistency with the experimental phase triangulation in Ti-Mn-N. The high melting refractory solution TiN1-x dominates the liquidus surface pushing all monovariant melting lines close to the Ti-Mn binary. |
