Thermodynamic assessment of the B–C–Si system

Experimental investigation and thermodynamic modeling of Hf–Si–B system

“…The work of Yang and Zhao and coworkers [28] for Hf-Si, the work of Rogl for Hf-B [29] and that of Chen et al [30] for Si-B systems fit well with available phase diagrams and thermodynamic data. Their optimized results were then accepted for the thermodynamic optimization with hope that we can extrapolate these binaries to the Hf-Si-B ternary system.…”

“…Thermodynamic data for Hf-Si, Hf-B and Si-B binary systems are taken from Refs. [28][29][30]. The thermodynamic descriptions for the Hf-Si-B ternary system developed in present study are listed in Table 7.…”

Analyzing the phase composition of Si-B and Si-B-Ti alloys based on silicon

“…The following coordinates were accepted in [5,6] for the eutectic transformation (Si) + melt SiB 6 : x(B) eut = 0.08 and T eut = 1658 K. At the same time, the corresponding values differ strongly, according to [7][8][9][10]: x(B) eut ranges from 0.08 [7] to 0.14 [10], while temperature T eut ranges from 1636 [9] to 1676 K [7]. The value of the eutectic transformation temperature obtained later in [11] by differential scanning calorim etry (DSC) coincides with the result in [9], 1636 K, and this value is considered to be reliable in this work. The thermodynamic properties of the Si-B melt and silicon hexaboride SiB 6 were determined in [12] using Knudsen mass spectrometry.…”

“…The considered rhombohedral phase can thus be represented by the formula (B 10,5 Si 1,5 )Si 2 or SiB 3 [24]. The authors of [6,11] considered that the identification of silicon boride as SiB 4 was due to the presence of a homogeneity region and the complex ity of its synthesis.…”

Computational Materials Design

“…[1] On the other hand, I became aware of the outstanding work of Zhangpeng Jin and Yong Du [9,10] long before I met them in person. However, the present conference booklet [11][12][13][14][15][16][17][18][19][20][21][22] displays more than a dozen important studies that Jin and more than 30 student colleagues have performed. These cover a wide range of scientific and engineering topics including amorphous Al-Fe-Zr alloys, [11] first-principles assisted assessments of Au-Co-Sn [12] and Al-Fe-Zr, [13] thermodynamics and CALPHAD modeling of TiO 2 -Y 2 O 3 , [14] B-C-Si, [15] Gd-Zn, [16] and Mg-Hg-Ga, [17] age-hardening of Ti-Al-N coatings, [18] experimental determination of Ni-Si-Zn ternary system, [19] CALPHAD study of Mg-Ag-Ca, [20] CALPHAD study of Fe-Nd-B and applications to sintering, metal spinning and levitation melting, [21] and predictions of interfacial reaction in multicomponent systems.…”
