【 摘 要 】

This article investigates the effect of various contents of Cr and Zr on the microstructure and properties of the alloy of the Cu-Cr-Zr system. It has been defined that an increase in the content of Zr leads to a decrease in the grain size both in the initial state and after severe plastic deformation. The increase in the content of Zr significantly enhances the strength of the alloy.
