Abstract
Materials that have been enhanced through traditional techniques like strain hardening, the addition of solutes, altering grain size through precipitation and refining are commonly utilized in industrial applications. However, there is a restriction on the extent of deformation that these traditional techniques can impose on a material. This research centered on examining the primary mechanical characteristics of aluminum alloys when polycrystalline materials incorporate an extremely fine grain size. By producing a high density of dislocations and then rearranging these dislocations to generate an array of grain boundaries, a high strain rate has an effect on the microstructure of aluminium alloys, converting coarse grains into ultrafine grains. Equal channel angular pressing is a manufacturing technique wherein a metal undergoes significant plastic deformation via simple shear, with no concurrent alteration in cross section of specimen with dimension. Using this technique, polycrystalline materials can contain an ultrafine grain structure. Instances are provided to illustrate the microstructural changes brought about by the ECAP process, as well as the resulting superplastic ductility achievable at extremely high strain rates. The microscopic structure and mechanical properties of an Aluminum alloy processed through ECAP, with a focus on varying channel angles like as . The utilization of ECAPed to the creation of an ultrafine grain structure in A5083, enhancing its formability. This material has established its reputation as a cost-effective, durable, lightweight option that enables achieving higher speeds. The mechanical characteristics of the samples were assessed at varying channel angles, and a comparison was made between tensile strength, misorientation angle, and hardness. The findings indicate that the processed samples exhibit reduced strength when compared to different channel angles like as and . ECAP was conducted using Route A, with a radius of curvature employed for up to four passes.
