Recycling of high grade die casting AM series magnesium scrap with the melt conditioned high pressure die casting (MC-HPDC) process

▶ MC-HPDC process shows excellent potential for the recycling of scrap Mg alloys. ▶ Intensive shearing alters the size and morphology of MgO clusters and oxide skins. ▶ Intensive shearing leads to the formation of fine and spherical grain structures. ▶ Intensive shearing eliminates dendritic microstructures. ▶ MC-HPDC Mg scrap properties compare very well to primary Mg alloy properties.
