Abstract

Transient unidirectional solidification experiments have been carried out with an Al-3 wt% Mg-1 wt% Si alloy under cooling rates ((T) over dot) in the range 0.2-45 K/s. A reverse cells > dendrites transition is shown to occur with the high-cooling rate cellular region associated with (T) over dot > 2 K/s and the dendritic region with (T) over dot < 0.8 K/s. Experimental growth laws correlating the cellular and dendritic spacings with the cooling rate are proposed. It is shown that the microhardness is directly influenced by both morphologies of the Al-rich matrix and by the relative fractions of Mg2Si and Fe bearing intermetallics that vary differently with the cooling rate.
