“…The most recent Co-Si phase diagram [25] exhibits the CoSi 2 , CoSi,  -Co 2 Si and Co 3 Si intermetallic phases of known crystallographic structures reported in [26], i.e., while the structure of  -Co 2 Si was not yet determined [27]. It is worthwhile to mention that the experimental data used for the optimization of the Co-Si phase diagram [24,25] are in good agreement within experimental errors.…”

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.

“…Previous studies included e.g. Al–Fe–Si [6] , Al–Ni–Si [7] , Al–Co–Si [8] , Al–V–Si [9] and Al–Mo–Si [10] . For the quaternary system Al–Fe–Si–Ti, literature data are only available in the aluminium corner and have been reviewed by Zakharov et al.…”

The quaternary system Al–Fe–Si–Ti was studied in the iron-rich corner for sections at 50, 60 and 70 at.% Fe at 900 °C. Isothermal phase equilibria were investigated by a combination of optical microscopy, X-ray powder diffraction (XRD) followed by Rietveld refinement and Electron Probe Microanalysis (EPMA). Phase boundaries of the phases, in particular of the Laves phase (Fe2Ti) and of the extended phase field of A2/B2/D03, were investigated. Selected samples containing the Laves phase and the B2 phase were characterized by microhardness measurements at different compositions throughout the quaternary homogeneity range of the phases.

“…As a consequence, two different AleCo phase diagrams were used in constructions of related ternaries. For example, the phase diagram suggested by G€ odecke et al [17] was considered in constructions of AleCoeNi [38] and AleCoeSi [39,40] diagrams, while the phase diagram proposed by Grushko et al [18] was taken into account in constructions of AleCoeFe [41], AleCoeNi [42], and AleCoePd [42] diagrams. Even though differences between the compared binaries are small, the incidence of an adapted incorrectness increases with the number of ternaries in constructions of which non-unified AleCo diagrams were used.…”
