Abstract
Coupled processes of dynamic recovery and precipitation, occurring during hot-rolling and subsequent aging, lead to the formation of a unique honeycomb network of precipitates in commercial Mg–Y–Nd–Zr or WE43 alloy. The honeycomb network is developed on the (0 0 0 1)Mg basal planes and consisted of fine Nd-rich β1 platelets lying on all three {1010}Mg planes presumably decorating recovery-generated dislocation subcell boundaries. Three variants of β1 platelets are connected by Y-rich β' precipitates at the nodes of the hexagonal honeycomb network.
