Abstract : The microstructure and mechanical properties of as-cast Mg-Zn-Zr-La-Y alloys were investigated. The alloys
were produced by low pressure die casting method. Microstructure investigations revealed that Y addition resulted in a
formation of Mg-Zn-Y phases generally expressed as three forms I-phase (Mg3Zn6Y), W-phase (Mg3Zn3Y2) and X-phase
(Mg12ZnY). After Y addition, the coarse Mg-Zn-La second phases were replaced by semi-continuous net-like second phase
structure, which coarsened with increasing Y addition. A considerable increase in the yield strength was observed after Y
addition but elongation to fracture was deteriorated due to the increased amount of second phases that may cause premature
crack propagation.
