Two complex ternary phases exist in the Mg-Zn-RE (rare earth) alloy system - an icosahedral quasicrystalline (i-) phase and a long period stacking ordered (LPSO) structure of magnesium. The symmetry or the complex crystal structure of these phases play an important role in strengthening of the magnesium alloys containing these phases. It is shown that the i-phase stimulates dynamic recrystallization and modifies the texture to produce high strength magnesium alloys with ductility. The LPSO phase containing alloys are known to have very high strengths.
LPSO phases show very fascinating structures, characterized by TM6RE8 clusters with a L12-type configuration. Structure of these phases determined by state of the art transmission electron microscopy are described, with implications for their stability and strengthening effects.
