The order/disorder transformation of the orthorhombic phase of the Al-Nb-Ti system has been modelled using the sublattice formalism with the aim of representing the thermodynamic properties of the two states, ordered and disordered, with a continuous

Phase diagram information and thermodynamic properties of mixing of the binary system Co-In have been determined by different authors. In order to optimize the binary Co-In system, available experimental data were critically compiled from the literat

Thermodynamic and phase diagram experimental data relevant to the Zr–O binary system have been assessed. A set of Gibbs energy functions describing the phases in this system is presented. The adjustable parameters of the models are obtained by leas

The phase diagram of the Pb–Tl binary system is experimentally well determined. Experimental thermodynamic values for all the phases involved are also available. For the liquid phase the temperature dependence of the enthalpy of mixing is also dete

In the Co–Ti system many solid solutions are present: A1, L12, A2, B2, A3, and Laves C15 and C36 phases. Two of them exhibit order/disorder transitions: A1 and L12, A2 and B2. In this optimisation the sublattice model has been used to describe the

A thermodynamic database, Zircobase, was developed for zirconium alloys for use in the nuclear industry. Two examples of the assessments concerning the Sn–Zr and H–Zr systems are given. The complete set for the binary systems, compiled or assesse

Calculated multicomponent phase diagrams were used to identify high speed steel (HSS) type alloys having the potential to exhibit enhanced sinter ability. The requirement was for an extensive austenite + carbide + liquid phase field. Of the six tungs

The Gibbs energy of formation of the solution and compound phases in the Al-Nb-Ti system were derived from an optimisation procedure using all the available experimental thermodynamic and phase diagram data. The thermodynamic description of the order
