【Abstract】 The precision shearing of Cu-Cr-Zr bars under radial clamping and axial load was put forward and tested.The influence of shearing parameters on the quality of shearing section was discussed,and the reason for the fracture zone was described.The basic principle of separation of Cu-Cr-Zr bar was investigated from macro and micro-morphology and stress state.更多还原
