A Study on the Application of a New Design for Equal Channel Angular Pressing Die and Design Parameters

Abstract

Severe plastic deformation processes are characterized by metal forming methods where exceptionally high plastic strains are achieved in a single pass due to elevated shear stresses. Additional passes during the process can further enhance strain values. Among the severe plastic deformation processes, equal channel angular processing is the most applicable method. The study introduced a method of applying equal channel angular processing in surface plating. Alloy strips made of AA5083 and Ms 58 Brass, each with thicknesses of 2 and 4 mm, were positioned alongside each other within an equal channel angular processing die. They underwent single and double passes during the processing to simulate the formation of metallic plating under cold pressure welding conditions. While some partial joints were observed. A new die arrangement has been proposed for equal channel angular pressing material processing. The suggested design represents an enhancement compared to current ones and includes an additional feature for processing materials at elevated temperatures, reaching up to 500 0C. The design underwent testing with various materials at different temperatures, demonstrating its capability to reduce the pressing load requirements effectively. The reduction in friction and the use of suitable tooling are credited for this advantage.
