Description:
The techniques of severe deformation of steel samples have been investigated – drawing and shear drawing in eccentric dies implemented at room temperature. The paper considers the features of structural changes occurring in low-carbon steel at different types of deformation treatment – conventional drawing and shear drawing of samples made of steel 10. The structural parameters and the nature of distribution of the plastic deformation intensity were investigated. Higher efficiency of the drawing process with shear was revealed in terms of strain intensity accumulation. A comparative analysis of structural changes and microhardness distribution over the bulk of samples produced by the investigated methods was conducted. The repeatability of the stress-strain state parameters obtained through physical and mathematical modeling was shown. The analysis of the obtained results leads to the conclusion that the use of drawing with shear is advanced for the production of samples and bil...
