Ni alloying is first adopted to explore the precipitation of quasicrystal phase (I phase) in Mg 96.5 Zn 1 Y 1.5 Mn 1 alloy containing LPSO structure and W phase during solidification. Results show the component of I phase is Mg 3 (Zn, Ni) 6 Y 1 which mainly distributes near the W phase. Besides, during the formation of I phase, Ni acts as Zn to participate in the precipitation process of I phase, making up for the deficiency of Zn. Meanwhile, an excellent strength‐ductility balance with ultimate tensile strength (210 MPa) and elongation (9.5%) is greatly optimized.
