The microstructure and properties of a quarternary Mg-8Er-5Zn-0.5Zr（mass fraction, %） alloy with the low Er/Zn mass ratio of 1.60 were investigated. It is found that despite of the low Er/Zn mass ratio, the microstructure of the as-prepared alloy is composed of α-Mg, W phase with face-centered cubic structure and long packed stacking ordered（LPSO） phase. As expected, the extruded and annealed alloy possesses high yield stress（310 MPa） and good elongation（14%） at room temperature. The superior me...
