| 中文摘要: |
| 目的 提高体积微成形件的成形质量。方法 利用等径角挤压工艺， 沿BC路径对T2紫铜试样进行了8个道次的挤压， 获得了延伸率高达56.7%的细晶材料。选择DEFORM软件对微小齿轮的成形过程进行了有限元分析， 得到了合适的成形工艺参数。结果 利用不同组织的材料， 成形出了最小模数为0.1 mm， 分度圆直径为1 mm的微小齿轮件。结论 实验结果表明， 与常规多晶材料相比， 细晶材料成形的微小齿轮的尺寸精度有了较大提高。 |

| To increase the forming property of micro massive forming parts，fine-grained T2 copper with an elongation of 56.7% was fabricated by using equal channel angular pressing， and the samples were extruded for 8 passes in BC path. The forming process of the micro gear was simulated by using the DEFORM software， and the proper forming parameters were obtained. Micro gears with a minimum modulus of 0.1 mm， and pitch circle diameter of 1 mm were well formed with different materials. The results show that the filling quality and dimensional accuracy was increased by using fine-grained material compared with conventional polycrystalline material. |
