Abstract

In this study, commercially available aluminum magnesium (Al 5083) alloy was subjected to equal channel angular extrusion (ECAE) up to two passes using route-Bc mechanical and wear properties of the alloy before and after ECAE were investigated to examine the effect of ECAE on Al 5083 alloy. Microstructural investigations were carried out along the flow and transverse planes of the extruded alloy using optical microscope and it revealed that the coarse microstructure of the alloy was refined to a considerable amount. The micro hardness and tensile strength of the alloy increased with increase in pass number. The wear properties of the alloy after ECAE were improved considerably along with improvement in hardness and tensile strength. It is clear from the results that the mechanical properties of the alloy were improved to a particular extent due to the highly refined grains imparted by ECAE process and it makes the alloy to be used in various engineering applications requiring high strength. at room temperature.
