摘要：

The sub-lattice model is used to describe the thermodynamic behaviour of the ordered phases existing in the Al-Ni system. The model parameters are derived from an optimisation procedure using all available experimental data. The order-disorder transformation f.c.c.-Al:Ll(2) phase is modelled using either two or four sub-lattices which are mathematically equivalent.
