The present work will present a complete assessment of the Fe-Pt system by means of the CALPHAD method. The liquid and the bee phase have been modelled as substitutional solutions where the interaction parameter is composition dependent in the form of a Redlich-Kister series. The ordered phases and the disordered fee phases were modelled in CEF formalism with a single Gibbs energy function. The obtained phase equilibria and activities of iron and platinum agree reasonably well with the literature data. Validation of the liquidus maxima around 50 at% Pt, found in the optimisation work, was performed by a quenching experiment followed by SEM analysis.
