本文对镁合金的晶粒细化进行了评价。等通道转角挤压用于加工商业纯镁。加工在523 K下进行，这低于文献上其他论文中使用的温度。对整个变形区的晶粒结构进行了评价。低加工温度防止了显著的晶粒生长。的晶粒结构的演变相比，最近的模型镁晶粒细化的机制。目前的结果证实了该模型的有效性。
Grain refinement in magnesium is evaluated in the present paper. Equal Channel Angular Pressing is used to process commercially pure magnesium. Processing was carried out at 523 K which is lower than the temperature used in other papers on the literature. The grain structure was evaluated throughout the deformation zone. The low processing temperature prevents significant grain growth. The evolution of the grain structure is compared to a recent model for mechanism of grain refinement in magnesium. The present results confirm the validity of the model.
