| Abstract Scope |
In the study a new process for the production of ultrafine copper and brass wires is proposes. The proposed process is based on the dieless drawing. The workpeace for dieless drawing is a thin wire (100 microns) obtained by a conventional drawing method. The proposed technology is based on the implementation of a multi-pass incremental deformation. Moreover, in each pass, strain and strain rate sensitivity of flow stress should be positive and significant. The deformation parameters in each pass are determined on the basis of an analysis of the dependence of the flow stress on the strain, strain rate and temperature. For this purpose, plastometric tests of copper and CuZn37 alloy were performed. For estimation of technological plasticity and wire surface roughness physical and numerical modeling of dieless drawing were performed. The obtained data were used in the practical implementation of the incremental dieless drawing technology. |
