Abstract：
Several grain refining methods of magnesium alloys in China,including those of liquid solidification,such as heterogeneous nucleation,rapid cooling,additional vibration and semi-solid forming,and refinement of grain in solid state forming process,such as representative equal channel angle extrusion method,high pressure torsion method,large strain rolling method were reviewed.The research progress and existing problems of grain refinement of magnesium alloys were analyzed,which provided some ideas for further developing green and efficient grain refinement technology of magnesium alloys.
