Conventional methods of manufacture enable constructional copper alloy parts to be produced with a porosity of 10–15%. However, such parts do not exhibit high electrical conductivity and corrosion resistance, good brazing qualities, and stability of properties with time and at ambient temperature fluctuations. To improve their characteristics, it is necessary to reduce their porosity to not more than 3–5%. This can be achieved by employing high-energy methods of densification, in particular hot and cold forging. There is therefore an urgent need to study the processes of deformation of sintered blanks, determine optimum chemical compositions of materials, and develop methods of determining optimum blank sizes and shapes for forging. |
