| Abstract: | The grain refinement technologies of magnesium alloys including carbon inoculation, the addition of Al-Ti-B master alloy, rare earth elements alloy, zirconium alloy and other alloy elements such as Si, Ca, Sr, Ti, etc are stated in details. Research status and the latest development of these grain refiners are reviewed. In addition. Refinement mechanisms of various refiners in as-cast magnesium alloys are analyzed emphatically. Finally, several new researching ways of grain refiner have also been given and the development trend is prospected. |
