Effect of hydroexstrusion on the structure and mechanical properties of copper M0b, pre-treated by equal-channel angular pressing
https://doi.org/10.22349/1994-6716-2025-123-3-31-37
Abstract
The patterns of the formation of submicrocrystalline structure of the grain type and copper properties under conditions of intensive plastic deformation and subsequent processing of hydroextrusion with varying degrees of deformation have been studied. It was established that with an increase in the degree of single-stage hydroextrusion to ε = 1.2, the strength level of copper M0b does not increase compared to its strength after equal-channel angular pressing. This indicates the beginning of the return processes and dynamic recrystallization of the material, which is confirmed by structural studies using electron microscopy and radiographic analysis.
