Equal Channel Angular Pressing (ECAP) is currently being widely investigated because of its potential to produce ultra-fine grained microstructures in metals and alloys. The objective of this work is to study the effect of ECAP on Al 6061 alloy. ECAP is processed using die channel angles of 90º, 120º and 140º. The stress and the deformation behavior of the ECAP processed material were investigated by hardness tests. The finite element analysis (FEA) is carried out for ECAP using PAM-CRASH software for different channel angles, which are prescribed in the experiment. The inputs such as material properties, loads, boundary conditions, contacts and controls were provided to the software and the results were visualized. The Von Mises Stress values obtained by FEA were found to be in good consistence with the experimental stress values.
