| 中文摘要: |
| 铝型材作为航天领域综合性能最佳的结构材料， 已广泛应用于各类航天器， 其中挤压铝型材产量占据总产量的30%左右。为获得合格挤压铝型材， 需要严格控制挤压工艺以及合理设计挤压模具， 挤压工艺包括材料化学成分、 铸锭加热工艺、 挤压速度等； 挤压模具设计包括模具材料选取和模具结构设计等。从控制挤压工艺以及合理设计挤压模具两方面出发， 对挤压铝型材成形关键要素进行简要分析。 |
| 英文摘要: |
| Aluminum profile is already widely used in various spacecrafts as the best structural material with the best comprehensive properties in aerospace. Hereinto the volume of aluminum extrusion is about 30% of overall output. It is required to strictly control extrusion process and reasonably design extrusion die so as to obtain qualified aluminum profile. Extrusion process involves chemical component of materials， heating process of ingot and extrusion velocity， etc. While extrusion die design includes selection of die materials and design of die structure，etc. Based on these two aspects，the main factors of the aluminum extrusion formation are briefly analyzed in this paper. |
