The research status of typical Dy-containing cast magnesium alloys was reviewed. The influence of Dy on the grain size

microstructure and mechanical properties of existing cast magnesium alloys was expounded. Meanwhile

the latest research progress in the mechanical properties and microstructure of Mg-Dy-RE and Mg-RE-Dy based cast magnesium alloys was presented

and the prospect of the research on the cast magnesium alloys containing Dy was also discussed.
