变形镁合金材料具有很大的发展前途与潜力,通过变形可以生产尺寸多样的板、棒、管、型材及锻件产品,并且可以通过材料组织的控制,获得比铸造镁合金材料更高的强度、更好的延展性、更多样化的力学性能,从而满足更多结构件的需要。[2]对目前研究尚不充分但很有潜力的AZ80变形镁合金的挤压、力学性能测试,以及对微观组织的分析等实验研究发现,挤压成形过程使合金发生动态再结晶,硬度随着挤压次数的增加而降低。
Deformation magnesium alloy material has great development prospects and potential, through the deformation can produce a variety of sizes of plates, rods, tubes, profiles and forgings products, and can be controlled by the material organization than cast magnesium alloy material higher strength, Better ductility, more diverse mechanical properties, so as to meet the needs of more structural parts. [2] The present study is not yet full but great potential AZ80 deformation of magnesium alloy extrusion, mechanical properties testing, as well as the analysis of the microstructure experimental study found that the extrusion process of the alloy dynamic recrystallization, with the hardness With the increase in the number of squeezes lower.
