Experimental study on the phase equilibria of the Ag–Ti system

The Ag–Ti diffusion couples were prepared by small pure silver plates closely packed in pure titanium powder, sealed in quartz tube, and annealed at 750 °C, 980 °C, 1100 °C and 1200 °C, respectively. The phase equilibrium relationship and the conjugate phase compositions in the Ag–Ti system were determined by means of the metallographic microscope and the electron probe microanalysis. Partial liquidus and solidus for the two-phase equilibrium, liquid + (βTi), were obtained. The narrow solution range for the intermediate phase (TiAg) was determined.
