Phase equilibria of the Mg–Ni–Y system were experimentally investigated through X-ray diffraction, electron probe microanalysis and transmission electron microscope measurements on thirty alloys. The isothermal section of the Mg–Ni–Y system at 400 °C was constructed according to the present experimental results. At 400 °C, thirteen ternary intermetallics including three long-period stacking ordered phases: τ1 (14H), τ2 (18R) and τ3 (10H), were observed. Their homogeneity ranges as well as the phase relationship were determined experimentally. The ternary phase of τ9 (Mg₃Ni₃Y₄) was observed for the first time in the present work.
