Abstract

Two zinc-aluminium based alloys with 30% Zn and 60% Zn and small additions of silicon have been quench-aged and the phase transformations studied in relation to the hardness. It was found that the peak hardness increase is due to the formation of αm ″ and α″ phases and evidence has been obtained for the transformation of these to αm ′ and α′. A cellular reaction αS ′→αT ′+η was observed in the first stage of ageing in the alloy with 60% Zn.
