The microstructure evolution of Mg96Y3Ni1 alloy with different Ti contents were investigated. Mg95.8Y3Ni1Ti0.2 alloy achieved finest grains, which was composed of alpha-Mg and long period stacking ordered phase. The ultimate tensile strength of Mg95.8Y3Ni1Ti0.2 alloy reached to 435 MPa with elongation of 21% after hot rolling and aging treatment.
