“…The lower solubility values following curve 1 were proposed to be more reliable than those following curve 2. Accordingly, the calculations by Witusiewicz et al [22] agree with the experimental data points reviewed in [15,16] well with curve 1. On the other hand, this contradicts with the maximum solubility of 0.91 wt% B assessed by Brewer and Lamoreaux [31] (see Table 4).…”

“…Figures 1 and 2 show the calculated phase diagrams of the binary systems of Fe-B [1] and Fe-Mo [15,16]. The agreement with the measured data of phase equilibria, activity, and enthalpy is reasonable, as shown in these assessments.…”

“…The thermodynamic description of the Fe-B-Cr-Mo system is shown in Table 3. The parameters marked with a reference code were taken from the earlier assessments [1,[11][12][13][14][15][16][17][18][19][20], and the rest were optimized (*O) using the experimental data in Table 2. The Gibbs energy data for the pure components are taken from the compilations published by Dinsdale [49] and Ansara et al [50].…”

“…The latter treatment is physically not as correct but cannot be changed, as already applied in the seven earlier descriptions of our Fe-B-X database. Second, the present descriptions for the liquid phase of the Fe-Mo and Cr-Mo systems, and the FeB phase of the Fe-B system, fixed in earlier studies [1,15,16], differ from those of [23]. A third reason is the present treatment of boride M 3 B 2 with a three sublattice model as suggested by Pan [24].…”

“…In this eighth part, thermodynamic descriptions of the B-Mo, Fe-B-Mo, B-Cr-Mo, and Fe-B-Cr-Mo systems are made using the experimental thermodynamic and phase equilibrium data from the literature. The binary thermodynamic parameters used in the quaternary Fe-B-Cr-Mo description are taken from [1,11] for Fe-B, [12,13] for Fe-Cr, [14][15][16] for Fe-Mo, [1,17] for B-Cr, and [16,18] for Cr-Mo, and the ternary parameters are taken from [1] for Fe-B-Cr and [16,18] for Fe-Cr-Mo.…”

Thermodynamic optimizations of the ternary Fe-B-Mo system and its binary sub-system B-Mo are presented. The Fe-B-Mo description is then extended to the quaternary Fe-B-Cr-Mo system by assessing the ternary B-Cr-Mo system. The thermodynamic descriptions of the other binaries (Fe-B, Fe-Cr, Fe-Mo, B-Cr, and Cr-Mo) and the other ternaries (Fe-B-Cr and Fe-Cr-Mo) are taken from earlier studies. In this study, the adjustable parameters of the B-Mo, Fe-B-Mo, and B-Cr-Mo systems were optimized using the experimental thermodynamic and the phase equilibrium data from the literature. The solution phases of the system (liquid, bcc and fcc) are described with the substitutional solution model, and most borides are treated as stoichiometric phases or semistoichiometric phases, using a simple two-sublattice model for the latter. The system's intermetallic phases, Chi, Mu, R, and Sigma (not dissolving boron) as well as boride M 3 B 2 , based on a formulation of (Cr,Fe)(Cr,Fe,Mo) 2 (B) 2 , are described with a threesublattice model. Reasonable agreement is obtained between the calculated and measured phase equilibria in all four systems:
