Abstract

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.
