Research of Combined Copper Processing Technology Including Heat Treatment and Radial-Shear Rolling

Abstract

This paper is devoted to the study of the influence of a combined technology, including both preheat treatment and deformation on a radial-shear rolling mill, on changes in the mechanical properties of M1 grade copper. The conducted studies have shown that after preliminary heat treatment, namely quenching at a temperature 500°C, and subsequent deformation of billets at temperatures of 20 and 200°C on a radial-shear rolling mill, an increase in the strength properties of copper is observed with a decrease in its plastic properties within the normal range. Also, according to the results of the conducted studies, it was found that the crosssection of the obtained copper bars shows a spread of microhardness values, which fully correlates with the data on the formation of areas with different microstructures after radial shear rolling in this cross-section.
