Changes in Microstructure and Mechanical Properties of Steel-Copper Wire During Deformation

  • Published:
Metallurgist Aims and scope

Currently, there are few works devoted to the change in the microstructure of steel-copper bimetallic wire during its deformation. Since steel and copper have different mechanical properties, these metals can deform differently at the interface. Therefore, the present study was devoted to the investigation of the effect of the equal channel angular pressing drawing process on the properties of bimetallic steel- copper wire. Deformation was carried out at room temperature in three deformation passes. It is shown that good hardening of the bimetallic wire occurs already in three passes, the tensile strength of the steel- copper wire increases from 580 MPa in the initial state to 812 MPa after the third pass. The yield strength increases from 380 MPa in the initial state to 562 MPa after the third pass. At that, the main increase in strength occurs in the first two passes of deformation.
