“…Where no data was available from the current assessment, tentative dotted boundaries have been included. These are based on information from the most recent binary assessments and the previous ternary assessments [6][7][8][9][10][11][12][13][14][15][16].…”

An isothermal section of the Fe-Mo-Ti ternary system at 1000°C has been constructed using data acquired from a series of seven alloys. The limit of solubility of Fe in the continuous A2 phase field between Ti and Mo has been determined, as have the extents to which Mo may be accommodated in the B2 TiFe phase, and Ti in the D85 Fe7Mo6 phase. The B2, D85 and C14 Fe2Ti intermetallics were found to have limited tolerance for non-stoichiometric compositions. The positions of the A2+B2+C14 and A2+C14+D85 three-phase fields were determined, along with the extents of the A2+B2, A2+D85, A2+C14, C14+B2 and C14+D85 two-phase fields. No ternary phases were observed in any of the alloys studied.

“…Many studies have considered the phase equilibria in the Fe-Mo-Ti ternary system [7][8][9][10][11][12][13][14]. However, there have been only limited experimental studies of isothermal sections in the system [13,14], which have been used to instruct thermodynamic assessments [8,14].…”

“…Where possible, tie lines were drawn between phases that were found to be in equilibrium. In addition, the continuous C14 phase field reported by Sokolovskaya et al [11] from Fe 2 Ti to Fe 2 Mo at 1173 K (900°C) was included, as well as the Ti-rich A2-A3 two-phase field at 1023 K (750°C) proposed by Shurin et al [13] At both 1173 K (900°C) and 1023 K (750°C), the A2 phase field was found to be continuous between Ti and Mo, with the solubility of Fe in this phase decreasing with increasing Mo content. For Ti-rich A2 compositions, good agreement was observed between the limit of solubility of Fe and that reported in the Fe-Ti binary system.…”

“…[7] However, very little experimental data exist regarding the phase equilibria at temperatures other than 1273 K (1000°C), and those studies that have been performed have considered only limited ranges of ternary composition space. [9][10][11][12][13][14] To address this issue, the phase equilibria that exist in the Mo-Ti-rich region of the Fe-Mo-Ti ternary system have been determined by examining a series of bulk alloy samples following extended heat treatments at 1173 K (900°C) and 1023 K (750°C). These data have been used to construct vertical sections between the A2 (Ti, Mo) and B2 TiFe phases, for Mo additions of up to 40 at.…”

Alloys with fine-scale eutectic microstructures comprising Ti-based A2 and TiFe B2 phases have been shown to have excellent mechanical properties. In this study, the potential of alloys with further refined A2-B2 microstructures formed through solid-state precipitation has been explored by analyzing a series of six alloys within the Fe-Mo-Ti ternary system. Partial isothermal sections of this system at 1173 K (900°C) and 1023 K (750°C) were constructed, from which the ternary solubility limits of the A2 (Ti, Mo), B2 TiFe, D8 5 Fe 7 Mo 6 , and C14 Fe 2 Ti phases were determined. With these data, the change in solubility of Fe in the A2 phase with temperature, which provides the driving force for precipitation of B2 TiFe, was determined and used to predict the maximum potential volume fraction of B2 TiFe precipitates that may be formed in an A2 (Ti, Mo) matrix.
