This talk introduces the derivation of alloy phase field models with complex order parameters that are derived from microscopic phase field crystal (PFC) models. Results from two recent studies in solidification made with such complex amplitude models will be presented. The first uses amplitude equations derived from the original PFC alloy model with two-time dynamics to study solute trapping and drag in rapid solidification. The second uses amplitude equations derived from the structural PFC (XPFC) alloy model to study the role of impurities in the continuous transition of solid-liquid interface anisotropy. Results are compared with experiment and molecular dynamics simulations.
