Phase equilibria of long-period stacking ordered phase in the ternary Mg-Y-Al alloys
文献摘要：
Phase equilibria focusing on the long-period stacking ordered(LPSO)phases have been experimentally in-vestigated in the Mg-Y-AI alloys.The microstructures of the eleven representative alloys annealed at 450,500 and 550℃ were systematically investigated using X-ray diffraction(XRD),scanning electron mi-croscopy(SEM)and transmission electron microscopy(TEM).Two thermodynamically stable LPSO poly-types were identified,including 18R and 10H structures.Meanwhile,the transformation of 18R → 10H was detected in Mg-9.OY-1.7A1(at.％)alloy,while the coexistence of 18R and 10H was observed in Mg-14.2Y-12.8A1(at.％)alloy.It was found that the LPSO phases were non-stoichiometric compounds with ternary solubilities.The 18R can dissolve up to 7.21 at.％-8.37 at.％Al and 10.75 at.％-12.01 at.％Y,while the 10H can dissolve up to 9.35 at.％-10.37 at.％Al and 14.50 at.％-14.94 at.％Y.All of the experimental re-sults were used to construct the isothermal sections,which is conducive to the design of Mg-Y-Al alloys.
