The dependence of the mechanical properties of Mg-Zn-Y alloys on the volume fraction of a reinforcing icosahedral phase (I-phase) has been investigated. The strength of Mg-Zn-Y alloys increases and the elongation to failure decreases with increasing I-phase volume fraction in the temperature range from 25 up to 200 °C. However, at a temperature of 300 °C, the strength of Mg-Zn-Y alloys decreases with the increase of the I-phase volume fraction, since the grain boundary sliding mechanism becomes dominant.
