Experimental Comparison of Al5083 Alloy Subjected to Annealing and Equal-Channel Angular Pressing

Abstract

In this study, the hardness and electrical resistivity of Al5083 alloy were investigated after equal-channel angular pressing (ECAP) and annealing processes. The effects of the annealing and ECAP processes on the properties of the alloy were investigated, and the results of the processes were compared with each other. The major reason for the different results between the two processes was changes in the microstructure, which were observed by optical microscopy and scanning electron microscopy. The results showed that, ECAP decrease the grain size, in parallel with it increase the hardness and electrical resistivity of material.
