Alloys with a range of combined strength and ductility can be designed by changing the fraction of the I-phase. Strengthening in proportion with increasing the volume fraction of I-phase can be explained by the effect of dispersion hardening due to the presence of finely dispersed I-phase particles. When quasicrystals exist in the a-Mg matrix as a second phase in Mg-Zn-Y alloys, the quasicrystals are stable against coarsening during thermomechanical processes such as hot rolling and high-temperature forming, due to the low interfacial energy of the quasicrystals with the a-Mg crystalline matrix, which provides strong bonding properties at the I-phase/matrix interface. Therefore, quasicrystal-reinforced Mg-Zn-Y alloys exhibit a much better combination of mechanical properties and formability than commercially used alloys such as AZ31 and AZ 61.
