Abstract
Phase equilibria in the ternary TiAgCu system have been studied thermodynamically and experimentally at various temperatures. The thermodynamic analysis was performed by combining the most recent data on the binary AgCu, TiAg and TiCu systems and experimental information obtained by the diffusion couple technique. The eutectic and three non-eutectic binary AgCu alloys were melted and annealed in evacuated Ti ampoules at temperatures of 900, 950 and 1000 °C for various times and subsequently quenched in water. Both the calculations and the experimental results confirm that in the ternary system there is a miscibility gap, which divides the liquid phase into solutions of low and high Ti content. Furthermore, no ternary compounds were found. Several isothermal sections and the activity of titanium as a function of the copper-to-silver ratio and temperature are presented.
