中文摘要:
      通过对闭挤式精冲零件进行金相观察，变形区流线和显微硬度分析，对闭挤式精冲加工中出现的一些材料微观状态的特点和规律进行了研究。
英文摘要:
      There are some differences between traditional fine-blanking and closed extruding fine-blanking in stress, separation process and the changes of material's performance. By metallographic observation and analyzation of flow line of deformation zone and microhardness of the closed extruding fine-blanking parts, the characteristics and rules of the micro-state of materials in closed extruding fine-blanking process are researched.
