| Abstract Scope |
Ab initio modeling of the thermodynamic and phase stability properties of alloys has generally focussed on binary alloys. In reality, however, most practical alloys have many constituent elements. Even when the alloy is rather dilute, such as in many actual aluminum alloys, it is rarely possible to consider an alloy as a binary. In the few cases where such a binary interpretation appears workable for the thermodynamic properties, it fails for a proper description of the kinetics. Here, solid solution phases with multiple alloying elements will be treated using cluster expansion methodology. The special features of the cluster expansion formulation which make it possible to treat large numbers of alloying elements will be explained and illustrated for some aluminum based alloys. |
