“…A similar behaviour has been observed for strongly interacting systems, such as the Al-Ni [41], the Ag-Hf [47], the Au-Sn [48], etc.., that exhibit strong heterocoordination around the stoichiometric composition of an energetically favoured intermetallic compound [31].…”

“…Accordingly, energetic and structural properties of Co-Si melts have been analysed in the framework of the CFM for strongly interacting binary alloys [31,34,48], assuming that the energetically favourable arrangement of Co and Si atoms is based on AB -stoichiometry. The mathematical details of the CFM formalism have been reported in [34,41,48] and in the following only the equations used to describe the mixing properties of Co-Si liquid alloys are given.…”

The knowledge of thermophysical properties of liquid Co-Si alloys is a key requirement for manufacturing of composite materials by infiltration method. Despite this need, the experimental and predicted property data of the Co-Si system are scarce and often inconsistent between the various sources. In the present work the mixing behaviour of Co-Si melts has been analyzed through the study of the concentration dependence of various thermodynamic, surface (surface tension and surface composition) and structural properties (concentration fluctuations in the long-wavelength limit and chemical short-range order parameter) in the framework of the Compound Formation Model (CFM) and Quasi Chemical Approximation for regular solutions (QCA). In addition, the surface tension of the Co 22.5 Si 77.5 (in at %) eutectic alloy, that is proposed to be used as the infiltrant, has been measured by the pendant drop method at temperatures ranging from 1593 to 1773 K. The results obtained were discussed with respect to both, temperature and concentration, and subsequently compared with the model predictions and literature data.

“…Surface tension has been calculated at T=1373 K. It is consigned in table 1 and plotted against the bulk composition with experimental data in figure 8. As can be seen in figure, the calculated surface tension for x Sn >0.5 shows a better agreement with those of Novakovic et al [20]. When compared with sutface tension literature data, a general agreement among data is poor.…”

“…Usually, the compound with the highest melting temperature persists in liquid phase, and the short-range order can be explained by the presence of cluster that has the same stoichiometry. [39], [20] and [40] respectively.…”

“…Sn-Au alloys are used as materials for lead-free solders [14] and have been found useful in flip-chip technology [15]. Surface tension of Sn-Au liquid alloys has been measured by many authors [16][17][18][19][20] at different temperatures. There is disagreement between different authors, especially concerning the existence of irregularities in surface tension isotherms.…”

The surface tension, density, and viscosity of the Ni-based superalloy CMSX-4 have been determined in the temperature ranges of 1,650-1,850 K, 1,650-1,950 K, and 1,623-1,800 K, respectively. Each property has been measured in parallel by different techniques at different participating laboratories, and the results are compared with the aim to improve the reliability of data and to identify recommended values. The following relationships have been proposed: density-ρ (T ) [kg·m −3 ] = 7,876−1.23(T −1, 654 K); surface tension-γ (T )[mN·m −1 ] = 1,773− 0.56(T − 1,654 K); viscosity-η (T ) [mPa · s] = 8.36 − 1.82 × 10 −2 (T − 1, 654 K).For a comparison, surface-tension measurements on the Al-88.6 at% Ni liquid alloy with the same Al-content as the CMSX-4 alloy were also performed. In addition, the surface tension and density have been theoretically evaluated by different models, and subsequently compared with new experimental data as well as with those reported in the literature. The surface-tension experimental data for the liquid CMSX-4 alloy were found to be close to that of the Al-88.6 at% Ni alloy which is consistent with results from the compound formation model (CFM).
