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)Mgbasal planes and consisted of fine Nd-richβ1platelets lying on all threeplanes presumably decorating recovery-generated dislocation subcell boundaries. Three variants ofβ1platelets are connected by Y-richprecipitates at the nodes of the hexagonal honeycomb network. [ABSTRACT FROM PUBLISHER]
