Abstract

The paper investigated the effect of cyclic deformation on the destruction nature of workpieces during broaching in step-wedge strikers. AISI 1020 was chosen as the workpiece material. According to the experiment results, the influence of turning and cycles number on the values of impact strength was carried out. Fractography analysis of the fracture surface structure was also conducted.
