摘　　要：叙述了镁及镁合金晶粒细化的几种方法,即合金化法、变质处理法、固态变形处理法、半固态成形法、快速凝固法及熔体搅拌法等。细化镁合金晶粒尺寸能显著提高其力学性能,这对推广镁合金的应用具有重要意义。The grain refinement methods of magnesium and magnesium alloys such as alloying method, modification method, solid- state deformation treatment, semisolidstate treatment, rapid solidification treatment, melt agitation method are introduced in this paper. The mechanical properties can be remarkably improved by refining the grain size of magnesium alloys, which is of great significance to promote the application of magnesium alloys.
