Abstract

SPD is a revolutionary process for converting bulk materials into ultrafine-grained (UFG) structures with outstanding flexibility and strength. ECAP (Equal Channel Angular Pressing) is a widely used SPD methods where workpiece is pass through specific die set. This will exert the significant stresses in materials without affecting their dimensions. In recent years, grain refinement through severe plastic deformation has gained lots of attention in scientific community. The most effective SPD procedures where extremely fine grain sizes and effective mechanical characteristics can be achieved is ECAP. Aluminium and its alloys are the most considered as most significant materials for a wide range of applications such as Manufacturing, Space vehicular system, automobile etc. The goal of this study is to explain the influence of different parameters such as die angle (channel angle, channel curvature), number of passes/ routes over Al alloy-based materials with appreciable reduction in its cross-sectional area. The impact of the Hot and Cold-ECAP procedures on the microstructure, mechanical properties, and wear of aluminium (Al) under load is reviewed in this article.
