CHANGING MICROSTRUCTURE AND HARDNESS OF COPPER ALLOY AFTER ROLLING AND HEAT TREATMENT

Abstract

Rolling technology is a metal forming in which material is passed through the pairs of rollers rotating in different directions. This process is not only changes the shape of the material but also changes its mechanical properties. Therefore, after rolling, heat treatment is carried out to improve mechanical properties of material. This article studies the changes in phases and hardness of materials during the rolling process of copper alloys, in addition to providing a suitable heat treatment process to reduce residual stresses and suitable mechanical properties for the material.
