Due to the excellent mechanical properties

Mg-Gd（Y） alloys have become important object of research and development. Its high mechanical properties are derived from precipitation strengthen. In recent years

the structure and morphology of precipitation in Mg-Gd/Y alloys have been investigated widely. The understanding of systematic characters of precipitation phase including structure and morphology in Mg-Gd（Y） alloys was increased

and the relationship between precipitation and mechanical properties could be easily mapped

providing a reference for developing high strength magnesium alloys.
