A review on impact route process on AA5083 of back pressure through equal channel angular pressing

Abstract

The goal of this research is to reduce the back-pressure needed to press throughout all channels. Equal Channel Angular Pressing has acted upon in a single pass at various temperature effects and with varying back pressure. To find result of specimens for investigating a back-pressure fracture. AA5083 samples were analyzed using an optical microscope to observe microstructural resulting from equal channel angular pressing. Hardness and tensile test data are used to analyzed mechanical behaviour. The microstructural characteristics, such as dislocation density, micro-strain, and crystallite size, are studied from the XRD peak profiles using a modified and distinct technique. The ideal processing parameter combination to press crack-free AA5083 through an equal channel is temperature of 220 °C and back pressure of 170 N/mm2. The processing of AA5083 using Equal Channel Angular Pressing under an assault of heated conditions and up to four passes of back pressure using various techniques has successful. According to the processing method and the number of passes, the microstructural, mechanical, and wear behaviour has been studied. After being subjected to the Equal Channel Angular Pressing process, the samples showed a significant degree of grain refinement as well as improved mechanical and wear resistance qualities. The mixed fracture mode, which is ductile and brittle, has validated by the fractographs of the tensile samples. The study of the X-ray line profiles shows that the enhanced mechanical properties are a result of changes made to the microstructure during equal channel angular pressing. It’s streamlined microstructure and greater microhardness, the sample produced using route BC displays superior mechanical and wear properties.[copyright information to be updated in production process]
