An analytical model for solidification of undercooled metallic melts

A model has been proposed for describing the solidification of undercooled metallic melts, on the basis that the solidification is considered as the sum of a liquid/solid cooling process without latent heat release and a latent heat releasing process without cooling. Application of the model to undercooled solidification of nickel, cobalt, zirconium, and Al–11.3Si–2Cu–0.4Fe alloy samples shows good fits to the temperature curves, and the fitting results of solid fraction curves are consistent with that from the available methods.
