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 and transverse planes. The microstructure of the alloy, which had previously been coarse, had significantly improved, according to the data. As more passes were made, the alloy’s microhardness and tensile strength increased simultaneously. The alloy’s wear qualities were significantly improved by the equal channel angular pressing technique, which also resulted in increase in hardness and tensile strength. It is possible that a material’s ductility during tensile testing does not fully reflect its capacity for plastic deformation. This study compares the state of an AA5083 alloy before and after equal channel angular pressing in order to assess the effects of the technique. The Hosford–Coulomb (H–C) model are used, the zone of equivalent strain to fracture was used to graph the fracture locus. Plasticity was examined using the Lode angle parameter and the stress triaxiality parameter. A robust correlation between the Lode angle parameter and the combined impacts of triaxiality and plasticity under stress in AA5083

Keywords: AA5083; SEM; Hardness; Optical Microscope, Fracture locus.
