The effects of rheo-diecasting on the integrity and mechanical properties of Mg–6Al–1Zn

An aluminium content of 6% offers the optimum combination of strength and ductility for Mg–Al based alloys. Mg–6Al–1Zn (AZ61) is one such alloy utilising this concept; however, it is not suited to high pressure die casting (HPDC) and has been used as a wrought alloy. We demonstrate that rheo-diecasting imparts high integrity and excellent properties to AZ61 while retaining all benefits of the HPDC process.
