| Abstract: | Principle of Equal Channel Angular Pressing technology was briefly analyzed. The structure of the die was redesigned. Some key technologies, such as the choose of the die material, lubricating agent were particularly discussed. It solved the problem that too much strength in axial direction will result in the distortion of bolt, which can even lead to the separation of the die.The die was designed simply and manipulated conveniently. |
