The microstructure and strength of quasicrystal containing alloys Mg₉₅Zn_4.2Y_0.8 (Alloy 1) and Mg_92.5Zn_6.4Y_1.06 (Alloy 2) was studied after extrusion at 523 K. It was found that the icosahedral phase particles act as strong pinning centres for grain boundaries and dislocations. Precipitation of ternary phase τ₁ and long β₁^′ phase rods occurs, imparting good deformation behavior at 473 K.
