[Display omitted] •Experimental dendritic growth laws are proposed for solidification of Al–Sn-(Cu;Si) alloys.•The Sn distribution is characterized by inverse macrosegregation profiles.•Hall–Petch type equations are proposed relating the primary dendritic arm spacing to hardness. The morphology and...
