“…[37][38][39][40][41] Stepien-Damm et al [42] reported a ternary phase Al 0.25 Fe 4.75 Mo 9 formed at about 1923 K. During the process of studying mechanical properties of Al-Fe-Mo alloys, [3,4] an isothermal section at 1273 K was constructed. Based on the above experimental results, Raghavan [43] assessed the Al-Fe-Mo system.…”

“…The mechanical properties of Al-Fe-Mo alloys have been studied by many researchers, e.g. Eumann et al [3,4] Knowledge of the Al-Fe-Mo phase diagram is significant for the development of Fe-Al-based alloys by providing information regarding the phases that are present at service temperatures, their compositions and volume fractions and so on. [5] In the present work, thermodynamic modeling and optimization of the Al-Mo binary and the Al-Fe-Mo ternary systems are performed using the CALPHAD method on the basis of the experimental data reported in the literature.…”

The Al-Mo and Al-Fe-Mo systems were critically assessed using the CALPHAD technique. The solution phases (liquid, fcc and bcc) were described by a substitutional solution model. The nonstoichiometric compound AlMo 3 was described by a two-sublattice model (Al,Mo)(Al,Mo) 3 in the Al-Mo binary system and (Al,Fe,Mo)(Al,Fe,Mo) 3 in the Al-Fe-Mo ternary system. Other comin the Al-Mo system were treated as stoichiometric compounds in the binary system and as line compounds Al m (Fe,Mo) n in the Al-Fe-Mo ternary system. The compounds l and Fe 2 Mo in the Fe-Mo system were treated as (Al,Fe) 7 Fe 2 (Fe,Mo) 4 and (Fe,Mo) 2 (Al,Mo) in the Al-Fe-Mo system, respectively. ) 0.235 Al 0.6275 (Al,Va) 0.1375 in the Al-Fe-Mo system, respectively. Ternary compounds s 1 and s 2 were treated as Al 8 (Al,Fe)Mo 3 and (Al,Fe,Mo)(Va) 3 , respectively. A set of self-consistent thermodynamic parameters of the Al-Fe-Mo system was obtained.

A new diffusion-multiple technique was used for mapping the phase diagram in the pseudoquaternary Fe 3 Al-Cr-Mo-C system at 800°C. The following five carbide phases were formed in an Fe 3 Al matrix phase (B2) with composition gradients of Cr, Mo, and C in the diffusionmultiple samples: j-Fe 3 AlC, M 5 C, M 6 C, Cr 7 C 3 , and M 2 C (M: Mo, Cr, Al, and Fe). It was assumed that B2 phase is in equilibrium with j, M 5 C, M 6 C, and Cr 7 C 3 but not with M 2 C phase at 800°C. Complex phase equilibria among those phases were efficiently mapped by the diffusion-multiple technique. The results from the technique were consistent with those obtained from the conventional bulk alloy method.
