Modeling structural transformations in binary alloys with phase field crystals

We develop a phase field crystal model for structural transformations in two-component alloys. In particular, the interactions between components are described by direct correlation functions that are an extension of those introduced by Greenwood et al. [Phys. Rev. Lett. 105, 045702 (2010)PRLTAO0031-900710.1103/PhysRevLett.105.045702] for pure materials. These correlation functions result in broad density modulations that can be treated with …
