Grain refinement can obviously improve the mechanical properties of magnesium

which is a approach to strengthen magnesium alloy. The effects of squeezing casting combining with squeezing deformation on the microstructure and mechanical properties of pure magnesium have been investigated. The results show that the fine and uniform equiaxed grain with 7.9 μm in average diameters in the pure magnesium can be generated

and its mechanical properties at room temperature are equivalent to that of T6 treated WE43AMB magnesium alloy

by squeezing casting at 150 MPa and squeezing deformation with squeezing ratio of 10.
