Abstract The grain microstructure is strongly bimodal due to the mixture of large dendritic grains that solidify in the shot sleeve and are subsequently injected into the die cavity, and the small grains that nucleate inside the cavity and grow to a size dictated by the solute content and the solidification rate. The large grains form only in concentrated alloys; their size is also partially controlled by the growth restriction factor.
