AbstractThe liquidus surface projection and isothermal section at 1,800°C in the Mo–Ti–C ternary system are examined using arc-melted alloys. A ternary transition peritectic reaction (L + Mo2C → Mo + TiC) takes place during solidification, which is apparently different from the ternary eutectic reaction (L → Mo + TiC + Mo2C) observed in a previous report. Since the composition of the eutectic reaction (L → Mo + TiC) shifts toward the Mo–Ti binary line with increasing Ti concentration, the volume fraction of the Mo phase and the interlamellar spacing of the Mo and TiC phases increase in the eutectic microstructure. At 1,800°C, the TiC phase in equilibrium with the Mo phase can contain more than 28 at% Mo and a Mo/TiC/Mo2C three-phase region exists at around Mo–15Ti–10C.

The phase equilibria among α-Fe, γ-Fe and Fe2Ti phases in Fe-Ti-Ni ternary system at 1473 K and 1373 K with Ni (γ former element) addition were examined, by paying attention to the γ+Fe2Ti two-phase region. The Fe2Ti single-phase region extends toward the equal-titanium concentration direction up to about 30 at% Ni, and the Laves phase becomes in equilibrium with γ-Fe by 12 at% Ni addition, but the γ+Fe2Ti two-phase region is limited because of the formation of liquid phase by further Ni addition at 1473 K. With decreasing temperature, a ternary eutectic reaction (L→γ-Fe+Fe2Ti+Ni3Ti) occurs, making the two-phase region wider just below the invariant reaction at 1373 K, and the region becomes narrower again by the enlargement of the three-phases region toward Fe-rich side.

Vertical Sections

A number of alloys have been examined microscopically. From these observations, from the equilibrium diagrams of the component binary systems, and from the application of the phase rule, a room temperature isothermal section has been deduced. Three vertical sections through the ternary system have been partially constructed from differential thermal analysis. These data show that invariant planes occur at 143, 148, 241, and 506 °C. From the information obtained from the vertical sections and the room temperature isothermal section, isothermal sections have also been proposed at 143 and 148°. The transformation at the 143 °C invariant plane is a ternary eutectic, at 148° a ternary peritectic, and the other transformations at 241 and 506° are also ternary peritectics.Some evidence indicates that the ξ-phase of Ag–Al system and the γ-phase of Ag–In system link up through the ternary system forming a single phase region, and that such may also be the case with the phases µ and α′ of the systems Ag–Al and Ag–In, respectively. The phases ε and [Formula: see text] of the system Ag–In do not appear to be capable of dissolving aluminum appreciably.

Primary Crystallisation

The phases occurring upon lead free soldering of copper substrates using indium, which contains for improved wetting additions of Ti, belong to the ternary system Cu-In-Ti. Thus, the liquidus surface of the ternary system Cu-In-Ti is determined using DTA data. Alloys were prepared from high purity metals by arc melting under pure argon. Before measuring the heating curves, all alloys were equilibrated at appropriate temperatures and XRD phase analysis were performed. A reaction scheme linking the phase equilibria found in the annealed alloys to the liquid phase is obtained. A projection of the resulting liquidus surface, which is dominated by the primary crystallisation field of the congruently melting Heusler phase t1-Cu2TiAl, is presented. In the In-rich composition corner the liquid phase solidifies in a ternary eutectic (In) + Ti2In5 + Cu11In9 at 155°C.
