| 中文摘要: |
| 通过Gleeble-1500D热模拟机获得AZ91D镁合金的应力应变曲线。采用刚塑性有限元法对AZ91D镁合金棒材挤压过程进行热力耦合数值模拟，分析了变形温度与挤出速度对挤压力和等效应变变化情况的影响。模拟的结果表明：在25∶1的挤压比下AZ91D镁合金的挤压温度为400 ℃，挤出速度为12.5 mm/s。 |

| The stress-stain curves of AZ91D magnesium alloy were gained through Gleeble-1500D simulator. The rigid plastic finite element method was used for the couple thermal-mechanical numerical simulation of the rods and bars extrusion process of AZ91D alloy. The effects of deformation temperature and extrusion velocity on the deformation force and strain-effective were discussed.The simulation results show that the extrusion temperature is 400 ℃ and the extrusion speed is 12.5 mm/s under the extrusion ratio 25∶1 of AZ91D magnesium alloy． |
