The Mg-12Gd-2Y-0.5Sm-0.5Sb-0.5Zr alloy was prepared under flux protection. The morphology and crystal structure of β′ precipitate phases in aged alloy has been studied using transmission electron microscopy and X-ray diffraction. The orientation relationship between β′ precipitate and matrix could existed as [ 010]BαB// [ 00]Bβ′B, (01 0) BαB// (020)Bβ′B and (0001)BαB was coherent with (001)Bβ′B; [0001]BαB// [001]Bβ′B, (1 00)BαB// (240)Bβ′B and ( 010)BαB was coherent with (0A_,8EEA0)Bβ′B. The HREM images indicated that the β' precipitates have a long-period ordered structure at the same time.
