The data of Rau (1967) on the H 2 S/H 2 ratios of gas in equilibrium with high digenite solid solutions permit the calculation of the activity of Cu 2 S as a function of temperature and composition. The activity of Cu 2 S falls to 0.5 when the mole fraction (in the system Cu 2 S-S) drops only to 0.87. These calculations also permit the estimation of the activity of S 2-temperature curve for ...

K respectively) determined earlier [12,14]. Substitution of Fe by Cu atoms leads to an expansion of the cubic lattice of TiFe. This Al-Cu phase diagram shown only goes up to ca 60%, by weight, of Copper. and is "split" at around 54wt%Cu by a particular phase. This "split" means that the two parts of the diagram must be considered separately. The diagram up to the 54% point is very similar to the "standard" phase diagram.

Thus, the Fe-Cu and FeCuB alloys solidified by natural cooling show two phases. These phases are a solid solution Fe-Cu and a small portion of Fe 2 B, as predicted in the phase diagram reported in ... the phase diagram from experimental thermodynamic data. The main purpose of the present study has been to do computer calculations of isothermal sections of the Fe-C-Si stable and metastable phase diagrams by using thermodynamic data from the three contributory binary systems. The C-Cu phase diagram [Massalski2] is of the simple peritectic type, with negligible mutual solubility between C and Cu. The C-Fe phase diagram [] is in the form of a double diagram, corresponding to metastable equilibrium with Fe 3 C (cementite) or stable equilibrium with graphite.The fcc solid solution γ (austenite) forms peritectically at 1493 °C. The pattern of the Cu-rich phase (bright) in the Fe-rich matrix (dark) is in Figure 1(d), comparable to the microstructures from Fe-Cu liquid separation [3,18, 36]. Further, Figure 1(e,f) shows ...
