Efficient metallurgicai and processing development requires ability to predict the solidification microstructure of products.Models were developed to calculate possible growth morphologies and phases in order to select the most efficient one for a given solidification condition.It is then possible to predict solidification microstructure selection maps (SMSM) indicating the microstructure as a function of the composition and the growth rate.Asummary of the methodologyof solidification microstructure prediction is given.Results obtained in a large velocity range for Al-Fe and Al-Cu systems are reviewed with experi- menta[ comparison and emphasis on the role played by metastable phaseequilibria in the modeiling.Finally.an outline of the actual work extending this approach to multicomponent alloys is given.Provisional cal- cu[ated solidification microstructure maps for the Al-Cu-Si system are presented.
