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.
