Thermodynamic assessment of the Au-Ti system

The Au-Ti binary system has been reassessed using the CALPHAD technique. With the set of optimized parameters a calculated phase diagram, which agrees well with all the experimental information including phase diagram and new thermodynamic data, has been obtained. It is shown that further experimental details are required especially for the liquidus and solidus of βTi at high temperature as well as the transformations between TiAu allotropes
