Evaluation of microstructure properties and characterization of fracture locus of AA5083 through equal channel angular pressing techniquesBy Nagendra Singh, Manoj Kumar Agrawal
Abstract: In this investigation, a commercially available aluminium alloy called AA5083 was subjected to two passes of equal channel angular pressing utilising a route B_C at room temperature for this experiment. To evaluate the effect of AA5083, the microstructure, mechanical attributes, and wear parameters of the alloy were examined both prior to and subsequent to undergoing this technique. Using an optical microscope, microstructural investigations were performed on the pressed alloy's flow …

Deformation Behaviour of the Billet and Tooling Design on AA5083 through Equal Channel Angular Pressing With Effect of Back PressureBy Nagendra Singh, Manoj Kumar Agrawal
Abstract: Equal channel angular pressing is an emerging method applied to subject materials to significant plastic strains while maintaining the original shape of the billet. Researchers have discovered that the level of strain attained through equal channel angular pressing is influenced by factors such as the angle of die, friction conditions, and the implementation of back pressure. These variables significantly impact the microstructure and the irregularity of strain within the billet …

Dynamic deformation and microstructural characteristics of AA5083 under the influence of electrochemical behaviour using equal channel angular pressingBy Nagendra Singh, Manoj Kumar Agrawal
Abstract: Large-scale Equal channel angular pressing is a great engineering material that has more potential for AA5083 industrial applications. Uniaxial dynamic compressive tests across a temperature of 448 K were conducted for the ECAP technique AA5083 in order to create such a design framework. The microstructure was described using transmission electron microscopy and scanning electron microscope both before and after dynamic loading. The plastic flow behaviour of the AA5083 was described …
