“…The use of secondary instead of primary magnesium alloys requires only a fraction of energy compared with primary magnesium production [1]. Thus life cycle assessment [2][3][4][5][6] reveals that magnesium is only a "green" metal if a considerable large amount of secondary magnesium is used, but recycling of magnesium post consumer scrap is not performed on the industrial scale and no defined secondary magnesium alloys comparable to aluminium secondary alloys such as A380 are available. The main reason for this is the possible up-take of heavy metal impurities during the recycling process with extremely detrimental effects on the corrosion resistance, but environmental and even economical issues require the development of secondary magnesium alloys.…”

The development of secondary magnesium alloys requires a completely different concept compared with standard alloys which obtain their corrosion resistance by reducing the levels of impurities below certain alloy and process depending limits. The present approach suitable for Mg-Al based cast and wrought alloys uses a new concept replacing the ß-phase by τ-phase, which is able to incorporate more impurities while being electrochemically less detrimental to the matrix. The overall experimental effort correlating composition, microstructure and corrosion resistance was reduced by using thermodynamic calculations to optimise the alloy composition. The outcome is a new, more impurity tolerant alloy class with a composition between the standard AZ and ZC systems having sufficient ductility and corrosion properties comparable to the high purity standard alloys.
