Compressive Behavior of Aluminum Alloy Aa6060 Subjected to Cyclic Extrusion and Compression Process

Abstract

Cyclic Extrusion and Compression (CEC) is one of the techniques of Implementing Severe Plastic Deformation (SPD) to polycrystalline materials in order to refine the grain size ranging from submicrometer to nanometer level resulting in improved mechanical properties of the material. In this work the influence of Cyclic Extrusion and Compression (CEC) on compressive behavior of Aluminum Alloy AA6060 is studied. The results shows that there is a significant improvement in the compressive yield strength of CEC processed samples compared to sample without CEC processed. It is also noticed that the elastic property increases from 68 MPa to 87 MPa, percentage of reduction in length gets reduces from 79 % to 56% and the compressive yield strength value increases from 210 MPa to 350 MPa at the end of 3rd cycle of CEC process
