Design of Die and Parameters for Grain Refinement of AA5XXX Series Through Equal Channel Angular Pressing: An Overview

Abstract: A material with low weight and great strength is a basic requirement of industry. There are a variety of approaches for improving mechanical characteristics and microstructure, but most successful demonstrate of ECAP method. One of the most well-known grain refining procedures for extreme plastic deformation is Equal Channel Angular Pressing (ECAP). The die plays a vital role in this procedure. Friction, Corner angle, the total number of passes, channel angle, routes, back pressure, and other variables can all influence the process's outcome. By Equal Channel Angular Pressing process variables that influence the mechanical equities of the AA5XXX series have been studied and analysed in this study for a better conclusion. Materials that have passed the ECAP test have improved mechanical, physical properties and micro structural Properties. The main alloying element for the 5000 series are Mg, AA5XXX alloys and their enhanced mechanical properties have become crucial criteria for their use for architectural and automotive trim, petrol tanks, high strength foil, dump track bodies, pressure cryogenic vessels, fittings and marine structures, components. Magnesium is the main element in the 5000 series alloys, and it is one of the most effective and extensively utilized alloying elements for aluminium. These are non-heat-treatable, moderate-to-high-strength alloys that are easily weldable and have excellent corrosion resistance, even in maritime applications.
